Answer 1

sand the dent with 400 grit sandpaper, then clean the area that you sanded with alcohol it will remove all waxes and solvents then mix the bondo and mix it well to remove as many of the air bubbles as possible, then apply the bondo as quickly as possible, once it begins to clump throw it away, for its already started to harden, also before starting cut a few cardboard squares about 10 inches by 10 inches so you will have these to mix the bondo on,, after you sand the surface smooth, you will more than likely notice tiny little pits through the project area, dont sand any further it will cause creases in the area, then you will need to prime these spots or the whole car with polyester primer, because polyester fills these tiny pores and will be easily sanded to smooth, final grit will be 600 wet, any finer the paint wont stick,any rougher you will see the sand marks happy painting

Answer 2

First and foremost, the less bondo you use the better. The holes your are talking about are for a dent puller. You drill holes into your car and screw in a screw about half way. Then a dent puller grabs on to the head of the screw. Now a dent puller is a shaft about 18" long with a cylinder type weight that wraps around it. You pull up on the cylinder untill it hits a stopper at the end of the shaft, the force causes the screw to pull up on the dent. You need to make quite a few holes depending on the size of the dent. You pull a little bit of the dent out on each one over and over untill you get it as close to normal as possible. next take a grider and smooth out the holes, cause they will be sticking up a bit. Then use the bondo. Slab it on thick and fill in the dent and smooth it out with the spatula that comes with it. Now, wait till it dries...COMPLETLEY!! Now use some 80 grit sandpaper and sand it down, use something straight & flexible, like a metal ruler, and see where your low spots are and repeat the process of adding bondo, drying, and using the paper and ruler untill you get it just right. Apply one more thin coat of bondo and use a 300 to 400 grit sand paper for the final smoothing. Spray it with a shiny primer and check your work again. The shine will allow you to see the imperfections. Finaly once it's all done, prime and paint. Good Luck!

Answer 5

Make sure you get as few dents as possible before you start with the bondo, the less the better. Apply it in VERY thin layers and let it dry, slowly build up to an even finish with the car. Then very finely sand it so you cannot tell the difference between the dent area and the primed steel area.

Answer 6

If the dents are too large, you might have to use a ding puller. You drill a hole or holes and then you take the ding puller and yank it out. If you pull too hard, beat it back with a body hammer.

As far as bondo is concerned, make sure the surface is etched and clean. When you think you have it smooth and are ready to prime, you can prime the area and then dust with another color of primer, or paint. This will let you see bondo scratches and pits. You can buy a tube of putty to fill any that are too large to be filled with primer. Finish sand with 400 or finer before painting.
I sanded my truck with 600 before painting it.

Answer 7

Make sure that you really follow the directions on the Bondo. If you leave little creases in the Bondo after you sand it and then paint the car you will see ripples in the paint job when the sun hits it right.

Answer 9

Take ur time and do it right. The process that u are planing on doing like prepping for paint is Extremely tedious it takes a long time if u going to do it buy itself. U have to take u time and sand everything down so that its all 1 smooth layer and this takes awhile and u can get anxious and half-*** it Also when u done painting it make sure u wet sand it to get that showroom shine. Make sure u go slow and keep in ur mind it going to be long work ahead also make sure u wear a respirator when sanding and gloves to u don't wanna breath in that dust u can buy 1 at a paint store

Answer 10

Work out the dents as much as possible. The less bondo, the better.
