I'm rebuilding the engine on my '69 Honda motorcycle. I polished the aluminum side covers. I thought about painting these parts with a Diamond Clear Gloss for bare metal. I also bead blasted the cylinder jugs, cam case, and head (all aluminum). I considered coating these with Diamond Clear Satin for bare metal. My question: is it ok to use a clear coat on an air cooled engine and if so, will these clear coats hold up to the high heat or am I creating a future problem? Worried about yellowing, peeling, etc. Thanks for any advice.
