- Hey this is Donnie Smith.
This lesson, we're gonnatalk about dent repair.
Now before we just jumpon this car and start repairing this dent, it'simportant for any repair job to wash it good withsoap and water to remove all the contaminants,the waxes and greases.
We've already done that,we used a power washer to clean the car and now we're using a wax and grease remover.
And this is just toassure that all the waxes and greases, silicones,things like Armor Alls that may have been sprayedaround the vehicle are removed, 'cause this will eliminatemany of the paint problems that arise during a repair process.
This will also save onsandpaper cause it won't be loading the sandpaperwith these contaminants.
Now we have the repair areaclean and we can begin repairs.
But before we do, we wanna take a look at the damage and seewhat's wrong with it, see where the indirectdamage is and direct damage, and determine what repairmethods we're gonna use to repair this damage.
Now when thinking aboutdamage, it's a good idea to think about water.
Because you know if somethinghits water it goes down, and when it goes down italso pushes a wave up.
So you've got the low areaand you've got the high area.
Think of damage the sameway, because any time there's a dent there's gonna be a low and there's gonna be a high.
So whenever you look at thisdamage, you can see that the center part of the dent isof course the direct damage, but then if you look up here on the top, you can see the crown, oreyebrow some people call it.
And you can see that that is pushed up.
That whole top of the fenderis actually pushed up.
So if you tried justto pull out on the low, or push down on the highthat's not gonna work.
You've got to roll themetal, you've gotta push down on that high while you'repushing out on the low.
Now, when you go todetermining what repair method you're gonna use, you mayhave some different types of tools, you may havesome high dollar tools, a stud welder gun, otherdent repair systems.
Where really what you wanna think of is what is the easiest method? If it's a hammer and dolly,you have access to both sides, then use a hammer and dolly.
Just because you've got thehighest piece of equipment does not mean you haveto use it every time.
Now on this particularrepair, if you drop the liner, you are able to get to the back side.
So if you can get to the back side, this would definitely be acandidate for hammer and dolly.
Feeling back there to see ifthere's room to get a dolly, which I determined that there is.
Another thing to remember isthat whenever you're repairing a dent to reverse what happened.
You wanna work from the outside in.
First in, last out.
So whatever happened first in an accident, that's the last thing you wanna repair.
Also remember whenworking with thin metal, it's thin, and you may be able to move some of this with yourhand some of the times.
Doesn't work every time, butI'm gonna reach back there and keeping that in mind that I'm gonna push down on that high,out on the low area, use my hands to rough this out.
Now this ain't gonna be perfect, it's just to rough out the damage, to get the majority of the damage out.
I can see that there arestill some highs and lows, I can feel 'em.
I know it's hard to see on the video, and even if you're doingthis yourself it may be hard to see this sometimes, butI've got a trick that'll help you locate the lows.
If you get a block withsome 80 grit on it, you can cross sand the damaged area, and what this'll do is that the highs will immediately go to metal, of course, 'cause they're high,but the lows, you'll see it doesn't sand it at all, andthis will identify the lows.
Now you can see the twolow areas very easy.
Now using the dolly, I'mgoing to reach behind this panel with the dollyand I'm gonna push out on those low areas.
Also, while I'm pushing outI'm gonna have to remember where those high areas areso I can tap in on those.
Remember, we always wannawork in multiple directions.
Whatever tool you're using, just remember to push out on the lowsand in on the highs.
Also, when using adolly, there's different dollies, different shapes.
You want the shape of thedolly to fit the contour of the part you're working on.
If this dolly was completelyflat it wouldn't work well with this repair.
Okay, now I am working on getting my dolly located on the back of themetal where I want it to go.
It may take a little bitof time to get it exactly where you want it, but I wantit right on those low areas, so that I can raise the low areas out.
Also while I'm raising lowareas out, while I'm pushing on them with the dolly, I wannatap down on the high areas.
This will allow the lowareas to come out while the high areas are tapped in.
This is called the Hammeroff Dolly technique, because I'm not actuallyhammering on the dolly.
The dolly is pushing out on the low, the hammer's pushing in on the highs.
There is also a Hammer on Dolly, and that's where youare hitting the dolly.
Any time you hammer on dollythat stretches the metal.
You wanna save that for your final stages, until you get the metalcloser to where you want it.
Then you can do some hammer on dolly for your final straightening.
So I'm gonna do a little bitmore metal straightening, and then I'm gonna use the block sander with some 80 grit on it tocontinue blocking that out to identify my highs and lows and see how the progress is coming.
Now whenever you're blocksanding with 80 grit to identify highs andlows, it's always important to cross sand.
By sanding in just onedirection, you're not gonna find all the highs and lows.
And this goes for if you're doing this to identify highs and lows,or block sanding body filler.
Cross sanding always levels much better.
Now we're using this sander,and this basically takes the place of what we usedto use with thicker metals, which is a body file.
However a body file will actually shave the top layer of the metalwhich would help level it.
We don't wanna do thatwith thinner metals.
We wanna use methods thatdoes not remove any metal.
So any method that you canuse that does not remove metal is always gonna be a better choice with these thinner metals.
Now I'm feeling out thedamage with my hand, just seeing what all highsand lows that I feel.
A little tip for feeling damage, because you'll have to do that often, is to use the flat of your hand.
Often I see fingertipsused, but that is not gonna catch the highs and lows,you're gonna miss 'em.
So always use the flatof your hand to be able to feel the damage.
Another trick that sometechnicians use is to use a rag, they claim that they can feel it better, it kinda eliminatesthe different textures.
You put a rag over yourhand and go over the damage and see if you can feelthe highs and lows better.
Try both ways, whichever works best is the method for you to use.
Now I feel a little bit ofhigh, so here I identified a high, so I'm just gonna tap that down with the pick side of the hammer.
I'm just basicallylowering that high area.
Now I'm going to re-blockit, re-sand it with this 80 grit to make sure thatit did remove the high area.
I feel of it, and I feelthat that feels good.
It's not perfect, butwith these thin metals, if you try to get 'em just perfect, try to metal finish 'emlike they did older metals, you're gonna weaken and thin the metal.
You wanna get it within 1/4 of an inch.
Anywhere between 1/8 and 1/4 is what most body fillersuppliers recommend.
However, you don't wannaexceed 1/4 of an inch, that's maximum after sanded.
You don't wanna exceed that amount.
This dent is well underthat, it's probably within 1/8 of an inch.
I'm noticing there's stilla little bit of a crease down here so I need to work that out.
I'm gonna get a hammer and dolly in there, I'm gonna raise in on the low area and I'm gonna tap this crease area in so that we can roll this metal back to where it's supposed to be.
As I'm pushing out with the dolly, I'm tapping in on that high area.
Now I'm being real careful herenot to hit the bumper cover.
It'd've been a better idea if I went ahead and dropped the bumper cover.
I'll probably be blending into that.
Another trick you can do is put a couple layers of masking tape.
I should've did that, Ishould've put masking tape or went ahead and dropped the bumper.
Because the last thingyou wanna do is sand into an adjacent panel,especially if it's not one that you're blending and cause damage that you have to repair.
I'm still having problemswith the low area right here, so I'm working on that.
Now the problem with this area, it's a little harder to get to'cause there's a brace there.
I'm following the same techniques, I'm gonna push out on that low area and I'm tapping around the high areas.
When I hammer on dollyyou can hear that ping, it makes a different sound.
You can hammer on dolly someto help remove that damage, but again remember thatthat stretches the metal and try to reduce theamount that you do that.
Little bit of a high, I knocked that down.
Okay, I'm gonna use my block with 80 grit to sand the damaged area some more to see if I got thedamage worked out enough to apply the body filler.
And I sand it and I feelof it, and there's still too much of a low there.
So I'm going to need to goback in there one more time and use the dolly and hammer.
I'm going to use the pickbecause there's a high here.
I'm pushing out on thatlow and I'm going to hammer on dolly a little bit,and sand it one more time to see if that has it.
And that's what it takes, itjust takes doing a little bit, feeling of it, checking your progress until you have thedamage where you want it.
We got the metal straightenedwithin 1/4 of an inch, really within 1/8, but 1/4 after sanded is the maximum amount of filler that most body filler manufacturers recommend.
No more than 1/4 of an inch.
That's the maximum amount.
I know 3M, Evercoat, they all have that on their technical data sheets.
So anything more than 1/4 of an inch you really need tostraighten it more than that.
You need to get it straighter.
Again, with these thinnermetals you don't wanna try to work it and work it,because you're gonna work-harden the metal.
It'll become work-hardened, thin, brittle, it may even crack on you.
It's almost impossible toget these thinner metals to do the metal finishingtechniques like they used to do where they'd work the metaland file it down and get it just perfect, prime it.
Now there is one exceptionto that, and that's PDR.
Paintless Dent Repair.
That's a total different set of techniques than we went over in this video.
This video is straightening metal like a body shop would perform.
Again, remember dependingon the extent of damage, like a fender, that wouldreally go into consideration, do we wanna repair that or replace it? Now on 1/4 panel, thosepanels usually cost more.
And also, it's a weld onpanel, so it's gonna take a lot of labor to replace it.
So you can have a lotmore damage in 1/4 panel than you would a fender,and still repair it.
Many times in body shops and dealerships, if there's even a couple ofhours of damage on fenders, they just go ahead and replace them, which is R and R, Remove and Replace.
Anyway, I hope you learnedsomething this lesson.
Thanks for watching, we'llsee you in the next lesson.
The cost of repairing small abrasions, cracks and holes in plastic bumpers is often much cheaper than replacing the part.
Of course, many collision repair technicians would rather replace the part and charge a fee for their labor plus mark-up on the price of the part because they lack in cosmetic repair skills and it is easier to warranty the work.
Working with Plastics
The first step to repairing plastic bumpers is to identify the material in order to choose the method of repair. Auto body shops use ISO codes on the parts to identify the various families of plastics. They cross-reference the codes with charts from the suppliers or by accessing reference materials on the internet.
It is important that the collision repair technician determine the type of plastic they are working with so they know the proper welding procedure to use to avoid damage to the part.
Some plastics can be welded with an airless welder or hot-air welder; others require a hot glue type of procedure. Tests must be performed and welding procedures have to be done correctly to avoid adhesion failure. Some bumpers will melt with a slight color change and they will remain tacky in the area where they have melted.
The bumper repair technician must identify the type of plastic they are working with in order to be successful with adhesive repairs. Failure to properly identify the plastic results in adhesion-related problems.
Some repair materials are based on flexible and rigid plastics. Using the wrong material can cause cracking when the part is flexed or it may not provide the correct strength for the repair area.
Cleaning and Prep
Proper cleaning and prep is critical for proper adhesion and finish. Whether the technician is repairing or replacing the bumper, the part will need to be cleaned. The bumper being repaired is likely to be dirty from the road; the new replacement part can have contamination on it from the manufacturing process.
Auto body repair professionals should use a low-VOC surface cleaner or a special plastics parts cleaner to help prevent solvents from going too deep into the plastic. If solvents are too harsh, they go deep into the plastic and cause adhesion problems after repairs are done.
This is an overview of the process of working with plastics. Time is money in the auto body industry; therefore, many collision repair technicians choose to replace rather than repair plastic bumpers and other parts.
Technology allows us to repair many items that are often replaced. As resources become scarce and landfills become over-full, we really should consider repairing rather than replacing when possible.
Who Really IS the Best Auto Body Shop in New Jersey ?
When you think of auto body shops, the first thing that pops into your mind is usually a place where you bring your car to after you an accident that needs some sort of collision or damage repair done; you might also think that an auto body shop is a place where you would bring your car to for some minor touch up work for various scratches or dents that have mysterious migrated onto your car. Thinking these things is by no stretch wrong but another thing that auto body shops perform is custom car modifications.
The realm of things that can fall into the category of custom automotive work are endless. Everything ranging from body kits to mufflers and even paint jobs can be perform by your local body shop providing they have the proper supplies and equipment for the job. As with all things, some auto body shops have a better reputation then others when it comes to do custom work. A good thing to keep in mind is the workload of the garage you are planning on visiting on any given time. If the body shop you are trying to use is full of customers, they might very well be able to do the work but the turn around time would be long. If the reputation of the shop is good enough then it is worth the wait and going through the hassle of making other plans while your car is being worked on.
After you have decided on the type of work you would like to have done to your car, you should specifically ask one of the auto body shops you have in mind if they can perform the job. If you have a fancy car that requires special tools of mechanical knowledge then it might be out of the realm of possibility for certain garages. It is also well worth it to research the auto body work shop you are planning on visiting in terms of any complaints filed against them before you bring your car in. The best way to do this is by looking on the Internet for reports filed against the shop you are interested in.
Before any custom work is done to your vehicle you should ask upfront for a clear cut estimate and to be telephoned if any extra work needs to be performed that is vital to the success of the original job request. If you have found a good garage, they would not do any extra work without your prior consent or agreement.
Caster, Camber, Tow-In - Wheel Alignment
One of the most important parts of your bike is the braking system. Without working brakes you would soon get into big trouble. Keeping your brakes in best shape is important. Fortunately, it is also relatively easy. Here is short bike brake overview.
Nowadays, you have three popular types of brake systems:
– Rim Brakes
– Disk Brakes
– Hub, or Drum, Brakes (including the Coaster Brake)
A number of other types of brakes have been used and are still used but they are not as popular as the three types mentioned above. Note that some recumbent bikes have no brakes. Obviously, don’t use such bikes in traffic. You may have noticed that track bikes are fixed-gear bicycles without any brakes. Actually, they don’t even have freewheel. But they are only used at a velodrome.
The old foot brake is not as popular as it used to be. It is also known as coaster brake and belongs to the drum brake category. The first coaster brake was invented back in 1898. The foot brake has one important advantage, since it is internal it works fine in all weather conditions. Foot brakes work for years without any maintenance but if it breaks, repairing it is generally very complicated. Since coaster brakes can only be applied to rear wheels, skidding is always a possibility. Another problem is that the brake can overheat if used too much. A practical problem is that the pedals need to fairly level, otherwise it will be difficult to brake. But combination of a hand-operated front wheel brake and a foot brake is efficient.
Mountain recumbent bikes generally use disk brakes. The system is simple, a metal disc is attached to the wheel hub. When the brake is applied, the pads squeeze against the disc. There are two types of disk brakes, mechanical and hydraulic. Disk brakes have many advantages but they are generally more expensive and heavier than other brake types. They tend to perform well in all weather conditions. They don’t overheat like rim and hub brakes when heavily used. Unlike rim brakes, they don’t heat up the rim and cause the tire pressure to increase.
Rim brakes are cheap, light-weight and relatively easy to maintain. The principle is very simple, two brake pads, typically made of rubber, squeeze the rim and slow down the cycle. You have a number of different models of rim brakes. The most common are Cantilever, V and center-mount brakes. Their main disadvantage is that they work badly in wet conditions. In muddy conditions, clogging can be a problem. They can also overheat the rim, which increases the air pressure in the tire. This could in worse case cause the wheel to explode.
Obviously, your budget will determine which stationary bikes are worth having a closer look at. Often the difference between the bikes is small, despite that the price difference is large. Although exercise bikes are fairly simply devices, some of them can get noisy after a couple of months. It pays off reading reviews from buyers of the stationary bikes you are interested in. For most people, the number of workouts you get with the bike is not especially important. Nowadays, almost all exercise bikes include the very few basic workouts you really need. More important is that the bike is sturdy, a flimsy bike is very annoying to use. Almost all of the exercise bikes from the well-known manufacturers are of good quality. But if you are thinking of buying a cheap exercise bike from an unknown manufacturer, make sure to test it thoroughly before buying it.
Note that especially recumbent exercise bikes are large and heavy, so it can be both difficult and expensive to return them. Thus, the cheapest bike may not the best exercise bike to buy.
