The Stovebolt Site Forums The Shop Area Paint and Body Shop cleaning panels

Hi guys lam going to start work on my 42 truck soon and was not sure if the panels and skins would stand up to sand blasting or if l should just rub the back to bare metal.
Cheers

Try and go with bead blasting and a primer coat included.
if you do not want a show room finish, i have opted to scuff up the paint and do the repairs, prime and repaint. Depends on the panel condition you have to start with.

I had my 39 cab and frame blasted. Worked very well but make sure the blaster knows what he is doing or he can warp the panels badly. He needs to use lower pressure and to jump around. If he stays on the panels too long it will generate alot of heat which will warp them. Ask him how long to blast your parts and then tell him to triple the time.

Maybe it's just my small homeowner sized air compressors, but I've never been near warping anything. I think I max out at about 75 psi and average about 50psi. I'm using beach sand.

I would do a chemecal bath on that old iron,a freind of mine did ,took his front end,fenders and inner fenders to a bath place and it came out great after I saw his stuff I wish I would have done the same, I took all the paint off with a drill and paint removing pads it came out good ,right down to bear metal but it took a long time and alot of work ,his stuff looks like new and did not remove any metal.

Acid bath is great however you need to rinse very well because if any residue of acid is left anywhere it will cause your paint to bubble later.
Sand blasting is ok if the person knows what he's doing like stea said.

Big Chevy, that is an excellent quote about coded information.

God bless.
