stripping paint from car, question

[ahardb0dy]

I'm in the process of removing some rust from my car and need to know the best non-chemical way to remove the paint and primer, I want to take it down to the metal. Today I spent most of the day doing half the hood using sand paper on a palm sander, I finally got it all removed but it took way too long. Any suggestions please?

Do you have a drill? They sell wheels to use with drills that knock off paint and rust, usually in the paint/body section of auto parts stores. They usually are brown in color and kinda look like a really rough sponge. I'm sure you've seen them befor as their fairly common. These work really fast, beats busting your hump with sandpaper.

I saw one of those today, like a real aggressive scotch brite pad, on a drill arbor, didn't know if they worked that good or not.

I used what they call a "Paint Buster" Its like a 8" DA sander (a good 6" DA sander would do it too), strips panels in minutes. Use 80 grit, then go over with 150 grit.

Will be kinda costly, as you would need the sander, a air supply (compressor)), and the sanding discs.

Dunno any other mechanical way to remove paint on large areas quickly other than this and media blasting.

I got a compressor, may have access to a D/A have to check, no more stripping till the weekend

You're half way there, sears has good d/a for what you need to do. Ask you local paint jobber for a backing pad and the d/a sand paper (3M or Norton) 80 and 150.

I've worked in Autobody (painter) since 1992.

Thanks, should I be applying some kind of sealer to the panels before the primer? I'm not concerned very much on a perfect paint job ( when I do have it painted) i just want to get rid of the rust, which so far seems like surface rust. The car is 19 years old and the paint is just old.

You'll want to apply a acid etch or zinc chromate primer before applying your primer coats. Check with your local paint jobber for your product details.

This will assure your build primer/sealer sticks to the metal.
