Anyone get any good ideas - the stuff doesn't come off with a wire brush, even on a drill, it just moves about, and I don't want to thin the underlying metal with a grinder. I managed to burn off some with an oxy/acetylene torch with excess O2, but its messy. I need a clean metal surface for welding. Maybe there's a solvent? Thanks for any suggestions Dean | ||

Would sandblasting work? | ||

A while back I saw some article on removing powder coat. I think it was on the web, but am not sure. The one recommended method was to freeze it with Co2, then chip it off, blasting with some kind of media might also have been recomended. If I find a link I will post it. -Reed | ||

I had a hell of a time removing the nylon coating on my roof rack. What I finally had to do was take it to a local company that does powdercoating. They placed the rack, legs and feet in their baking oven and baked the whole thing for about five hours. Then they were able to sandblast all the coating off. Prior to that I had tried mechanically stripping, chemicals and plain old sandblasting but the coating wouldn't give. | ||

Thanks for the ideas. I gotta give it to land rover, that plastic coating is one tough little mofo. I only gotta get a few square inches off the corners so I can weld on some tabs, but its in a really visible place. Dean | ||

FYI that's not powdercoating. It's actually a plastic that's more expensive than powdercoating but doesn't hold up well once rusts gets under it. I stripped down my entire brushguard using a pneumatic die grinder. Sandblasting would cause pitting in the metal. I had some rust in places so it readily chipped off there. Good luck. Brad | ||

I removed all of the plastic coating from my brush bar very easily once I found the secret. Heat it slightly with a propane torch, I did about a one foot section at a time, cut through the plastic with a sharp knife and just peal it off. It comes off in large pieces. I heated it just enough to allow it to peel off. I was able to do it without gloves but it was slightly uncomfortable at times! I think that a good heat gun would also work well but I didn't have one to try. | ||

Brad, The pitting caused by sandblasting is called the anchor pattern as it's the anchor that holds whatever type of coating your apply after blasting. The size and depth of the pattern is adjusted by changing mesh size (size of individual abrasive media), changing media ( I've seen everything from walnut shells, to glass beads to BB's) and adjusting the output pressure at the nozzle. If your local blaster says he can only provide one type of anchor pattern no matter the base metal then it's time to find a new blaster that will listen to you. Cheers Andy | ||

Andy, Thanks for the info. I work at a body shop. I'm 18 and just getting into working on cars so I'm a newbie with a lot of stuff. That's just what someone had told me, so thanks for clearing it up. |
