im slowly painting an old logan lathe, I just used rattle can (ace machinery gray) which is almost positively rustoleum worked out great for most of the lathe only issue I have is the carriage where hot chips land is getting some pits.... ive seen some clear coats in a spray can which say there for high heat and oil and gas resistance. was wondering if a coat of this would fix my problem? ya I know a good brush on paint would probably be better but who has the time. anyone try these clear coats? I was even thinking the high heat paint for engines but couldn't find machinery grey...most are orange or red it seems.
