Well, I found something that works pretty good. Wet sanding with emory cloth works very well. Looked into the sandblasters, don't think my air compressor can handle them. Plus the Harbor Freight guys pissed me off. As to painting, I am going to rattlecan the frame. Primer first, then flat black. Couple of coats of each with the krylon. Then I think I will rough that up with an abrasive pad and put a couple of coats of herculiner over that. By the way, I am speaking of the jeep cj5. I am perfecting my method with it, then I plan to do my ranger. All I can say is that I am glad that I live in New Mexico, we have to be about the best state for low oxidation. I don't know what you all know about jeeps, but the fact that the factory original gas tank skid plate just has a little surface rust is AMAZING for a beat up 1979 amc. My jeep will be worth a lot someday just because of that.(Especially when I get done restoring it!!) Most of the originals probably were gone by the early 90's.
Anyone had any experience putting do-it-yourself bedliner on a frame?
