Ok. I was following a thread about prepping and painting valve covers. I can't find it but have a question. I removed them, decreased them with dawn and laundry detergent and water. After that, I wiped them down with denatured alcohol. There is the big mistake. The original paint began bubbling and I was able to wipe the paint right off in places. Ugh. I immediately rinsed them in clean water and the paint is now stuck back in places. I thought that after wiping with the denatured alcohol, I could just high temp paint.
Probably, the best move would be to remove all original paint and apply the new coat of paint. Where did I go wrong?
Denatured alcohol should not have caused the paint to lift off. My thinking is that the paint wasn't applied correctly to begin with. You probably did yourself a favor. I've usedn rubbing alcohol on paint to remove stuff like tree sap and never had a problem. Lacquer thinner would be a different story. The original paint was not high temp and I do not think you really need it. Won't hurt to use though.

Reason: Adding more info
Thanks. I'm more confident about the outcome now that I got some feedback. The reason for painting was more of a chance to do it while I was there. I was replacing the gaskets and grommets. I'm not going for show quality, just cleaning up.
They look pretty good from here. What carburetor do you have?
I don't know. I'll check when I get home. The guy at Napa came out to look under the hood and saw the carb. He said that he buys them and rebuilds them to sell so whatever that means.
Thanks for the compliment on the paint. I'll tell people to keep back while looking. I have to touch it up since the paint wasn't completely dry when I put them back on. I was in a rush with the rain and all.
