I believe I'm going to paint the engine Rustoleum High Heat (2000 deg. F.) rattlecan.

Should I prime it with High Heat (also 2000 deg F.), or will that make the engine trap too much heat during routine driving?

I'm no expert, but I've had pretty good luck with paint sticking directly to cast iron.

Oh, and I don't believe the high heat paint is needed. Your engine block probably never reaches 300, much less 2000.

I use Rustoleum satin black. It looks good, resists oil & fuel, and needs no primer.

Hal, good point about the block.

How hot do you suppose the head gets?

I've painted more engines with Rustoleum than I can remember.

Done it with primer and without primer. Can't say that it ever made any difference.

And for what it's worth, I've never used the high heat stuff...just the straight up plain stuff. And it's held up fine.

If you use designated engine paint, it has primer already mixed in the paint. Clean engine real well and oil free .

I used Rust-Oleum black gloss engine enamel in a spray can. Wire brushed the engine a bit and sprayed it on. Sticking well so far...

Don't have a full engine photo on hand but here's a partial shot of the head.

I could only guess, Bill, but I've never had regular spray paint burn off or even discolor on a head. Exhaust manifold? Yes.

Your head will only get as hot as the water running through it.

George hit it on the head: surface prep is the key to any good paint job. It's a pain and slows down the work, but without clean surfaces paint won't stick worth a darn. I've used Dupli-color ceramic semi-gloss engine paint with pretty good success for rattle can stuff. Seems to stick pretty well to aluminum heads as well.
