Engine enamel in a spray can works great for me. I have used I think it is Duplicolor, brand, Just look for engine enamel at an auto parts store, or hardware store. for best result you need to degrease the tin and sand. the old paint may have a lot of oils trapped in it, making adhesion an issue. The engine enamel resists many automotive chemicals, and dries fast. I prefer it to rustoleum for this application, however rustoleum has worked ok also (do not mix the two, and rustoleum take much longer to dry and longer for recoat time.

so clean clean clean, sand then follow the spray can instructions, pay close attention to recoat times, and you should be golden.

I have spray painted many an engine tin and it holds up so well, that even DECADES later it is still nice.

powder coating is an option, but frankly I have not been too impressed by it. It is costly and it too can fail.

With the spray can you can also do quick touch ups to a perfect match if you scratch the finish

So Duplicolor Engine Enamel is my first choice for cooling tin and intake runners.

High temp paint is needed for things like the muffler or heat exchangers, that is what I use there , for that I often select rustoleum BBQ high temp paint.
