When using high heat ceramic paint on air cooled bike engines, there was three reasons:

1. Ceramic paints should help dissipate heat from the cylinder. Not much, but a little bit. In particular if you use flat black.
2. Because you aren't in there ever day, your cylinder fins will get coated with crap. Ceramic paints stop surface corrosion and do an excellent job of stopping dirt and liquids from sticking to your cylinders. (Which in my opinion will do more to stop heat build up and promote good cooling than anything else)
3. Its just looks nice.

I have also heard of cermic coatings being used on piston domes. (not $5 paint but special ceramic coatings)


I have been surprised by the number of porsche motor pictures I have seen, and no one seems to have touched their cylinders with anything but bead blasting.

(Or have I just missed alot of pictures?)
