i need to start the body work on my car

ok well i got a 82 grand prix wich ive had for a year now but just sitting in the garage for me to work on. when i got the car there was surface rust all over and so i did the body work on the whole car. used a little electric sander and sanded it all down and used cheap bondo and rattle can primer. what a waste of time and money.

i want to redo the whole car over and use a good body filler, weld in some sheet metal in the rear quarter pannels where they have roted out , and primer it with a good epoxy primer.

ok so what are the steps?

1.remove all paint - Q:Can i use a angle grinder with 80 grit sand paper?
2. weld sheet metal were rust has taken over
3. epoxy primer the whole car
4.use body filler in low spots
5.primer again - Q:whole car or just over body filler?
6.paint on base coat
7. cover the car in clear cote

am i missing anything or is that wrong way of doing it? please reply. dont want to waste my time and money like before.

Looks like you have it all figured out! Only thing I would suggest is use and 80 grit on a DA instead of grinder. The spray primer will come off real easy. Grinder OK, IF you know what your doing with it, but I think it would be over kill except for using in rust areas.

Use a Da to strip the paint off. I have an 8" orbital da that is a big time saver, and I start with 36 grit, and then go over the metal with 80 grit on my 6" DA to smooth out the scratches. You can do it either way, epoxy primer down first then plastic filler and epoxy again over the top, if the epoxy sits more then a few days, it will have to be scuffed. Or you can grind the metal up a little, apply your filler and sand then epoxy prime. You can then spray urethane filler primer over the epoxy after a little while, probably around a half hour to an hour. The tech sheets for the product you are using will give you the time. I believe most epoxy primers you will have to apply another primer over the top, the epoxy's are really more for protection of the metal or a sealer, and don't sand well. If you are priming the whole car, spray a few coat of urethane primer on it, and block sand it before paint.

alright cool thanks!

question about the DA sander thing... can u buy them in electric versions or only for a air compressor? i just bought a 5 peak Hp, 20 amp, with a 20 gallon tank, campbell huasfeld air compressor. but it doesnt nearly have the rated scfm as a DA sander.


i think il strip the paint then epoxy then filler so i can see the low spots good.

Does anyone In Canada know of a store that sells like PPG and evercoat products? i have no idea where to go, ive ever been for car related is canadian tire and auto value pretty much.

If the rating on the craftstman da is really that high, seems like a lot, look at different brands. I just did a quick search for 6" da, and most were rated at 5-6 cfm at 90 p.s.i. which falls right within what you stated your compressor puts out. I have a old craftsman da and don't know what the ratings are on it, long lost them, but I don't even think my 7 1/2 hp compressor puts out 13 cfm at 90 p.s.i. and running my 6" da on it doesn't even phaze it. My 8" snap-on orbital is a different story, the compressor runs and charges up a bit when running that.

I just got done with the body work on my car and the DA is a must. I use the Campbell and Hausfeld DA as well. You have about the same compressor I have and that little guy will have you sweating! The DA with 80 grit will take the paint off very well, even with your compressor. You will only be able to work for a few minutes at a time though. When I did mine I used a paint stripper wheel in my 1200 rpm drill to cut the paint then I went back over it with the DA to strip and smooth it out. This way I could switch back a forth between the two tools while the compressor filled up. Keep an eye on your compressor to make sure it doesn't get too hot and burn up.

They do make electric DA sanders, but they're not very common.

I'm still learning about all of this, but I was on a limited budget and had to make do with what I had. Bottom line, it can be done if you are patient!
