Re: Removing Engine Paint for New Paint
I've found that oven cleaner is good for grease but it didn't do much, if anything, for paint. It left the original black paint on oil tubes untouched after the grease was gone.
I scraped my block with a heavy putty knife type scraper to chip off the easy stuff, then used aircraft paint remover for the difficult to reach areas and pores in the block. Next I used a wire brush on a little side grinder tool I have. That cleaned up the block pretty well. Next I brushed on a degreaser and ragged it off until the rag didn't show black residue. Finally I masked off some areas and brushed on a couple coats (maybe 3) of engine paint. The paint flowed out well and showed no brush marks.
I wouldn't use a sandblaster anywhere near an engine. Seems like no matter how well you think you protect the engine the sand will find a way in there. Just my opinion.
