It's to cooled to take it outside for sandblasting. The rust is thick and i've tried phosphoric acid, didn't work to good. DA sander glazes up in about 30 seconds. I'm sanding by hand using sanding screens, they work the best but very very slow. Anybody have any ideas.

Do a web search for them as 3m sandblaster grinder pad. They used to have them at lowes. I have also used knotted wire brush on grinder. I did that on my jeep, but the hood was so pitted and stinky that I painted it with zebra stripes so you couldn't see it! | | | | | Joined: Feb 2005 Posts: 355 Member | | Member Joined: Feb 2005 Posts: 355 | An angle grinder with a Scotch-Brite pad will zip it right off. They carry them at the local home stores here AND you can get them from www.eastwood.com | | | | | Joined: Oct 2005 Posts: 69 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2005 Posts: 69 | I'm trying all your suggestions and it's working like a charm. I had tried using my angle grinder with 60g paper, if one second in a spot is good then two seconds is better right. I had a small heat warp to fix so I put the andle grinder back in the tool box. Now I,m using my 5" with a wire wheel then the 4.5" with a multiple angle layer sanding disc. I wet sand with soapy water and a scotch brite followed by the DA sander wet a couple of times and it shines like a mirror. Then I acid treat it to stop the rust from coming back. I guess kept trying to you get it right. Thanks a lot guys, it takes 5-6 minutes per sq foot, before it was 45-60 minutes and still had rust marks. Anybody think I should spot putty as I go or prime first, the little dings and scratches show up real good now. Again Thanks.
