Sandblasting is by far the best way to go. Sure you can paint over the paint you have but most of the time your results wont be as nice or last as long.

And YES sandblasting CAN warp the metal. I occasionally sandblast and have done car bodies. Thing metal will warp. Get someone who knows what they are doing and has done car bodies before. Sand it, blow it off with compressed air, clean the metal with some sort of mineral spirit, and prime it and paint it. Preferably indoors.

Bringing history and technology together.

to me sandblasting is a big nono.
don't let annyone say it won't warp your panels because it will!
and to those who say it won't have you ever blasted in total darkness? its fun you will see sparks flyin' now I may be a fool but I never knew sparks are cold.
second reason is: that sand will get everywhere!
it accumulates in places you cant get it out again, gets wett and guess what happens next, yep rust.
the second thing I observed is what is it with that "get all the paint off" thing?
if the original paint is still good leave it be!
sand it and paint it, nobody will notice the original paint is still under there if you did a good job.
taking all the paint off is taking a risk. here you have a sound panel whithout any rust on it and what do you do? you get all that protection off so it gets the chance to rust.
and trust me, surface rust, it don't take days to build, it takes minutes! yep you cant see it after an hour but take a rag with some thinner and wipe that panel, then take a look at your rag what do you think that fuilt is on the rag? I'll tell ya its rust.
but all this is my idea. its your car, do what you want with it.

if u have a previous paint job on a car and the body lines are good and its straight as an arrow u can take a DA(dual action) with a 320 and go at it then a 400 scotch brite pad, degrease then paint...if ur just trying to work rust out try a nuematic filer...just watch ur plane surface so u dont cut at any radical angles...chemical stripper would get u down to BARE metal and there's no reason why u couldnt paint over an old paint job as long as u seal any more questions e-mail me at or icq 23175985

I usually strip paint panel by panel with a chemical stripper. If the panel is removable I take it off and set it on a stand, this way I dont get the stipper on other panels, especially ones I just primered. If there is any paint left that the remover didn't take off, I take a DA with 180 grit and sand off whatever is left.

I've come across a relatively new product from 3M. It is a 36 grit surface conditioning pad. It looks like a purple Scrubbie on steroids and fits a 4" grinder. Cuts paint like mad and, because of its open construction, does not load up like sandpaper.
