Engine tin and shroud paint

Should I use high temperature paint on the engine shroud and tins? or will good old rustolem work,

I've used Rustoleum spray cans on the vaned parts of VW cylinders and on tranny cases before. No problems at all.

Don't use the Rust Oleum High Heat paint; it's too powdery and the finish won't be satisfactory. Believe me, I've been there. Use regular engine enamel (it's heat resistant but not in the "high heat" category as for mufflers, etc.). You'll get a nice finish that way.

Chuck, You can't beat poly paint. Visit an auto body supply shop and ask for;

" a single stage poly. (two part) paint" and a batch of "preval sprayers" .
Put on your respirator, scuff your engine tin, mix and thin the paint, pour into the disposable sprayer, try a test piece. Then get busy. A little more effort but you can't
beat the finish and durability with a "rattle can". But if you don't want to bother
the paint brand "Hammerite" looks and lasts great and dries to a baked on enamal
look=wow. Good luck.
