Finally got around to pulling the spare engine from my parts car. It's a little bit more rusty than I originally thought. On festivas there's a spot between the downpipe and front of the engine that's basically open to the elements. The plan is so far degreasing it/pressure wash, take the dremel with a wire wheel and rewash afterwards, put some rust stop, prime, and paint it with Duplicolor ceramic engine paint. Is rust stop a good product to use on engine? I haven't found any engine primer, will any primer work?
