painting engine bay components question
Will regular rattle can paint ( ie: Rustoleum/ Krylon) non heat type hold up doing the pulleys,brackets,etc. and maybe other items that are attached to the engine ? I'd be upset if all the hard work blistered or cracked under heat. Just don't know the temp rating of these paints. Thanks for any answers! Mike

DUPLI COLOR,
ENGINE ENAMELS are available in LOW, SEMI and GlOSS Black that work PERFECT for the varied sheens used within the engine compartment.
I've been using them for years and they layout really nice and hold up fantastic to repeated heat and cleaning cycles. My '66 was refinished years ago and has held up very well with little to no point up. And yes I drive it and have conducted overhauls.

I love the valve covers on those OHC 6s!
That casting must of been 1/2 the additional cost of that whole top end set up! Pontiac had that Cam belt drive pretty much well worked out by those years and I really which GM would have let them do atleast a OHC 389 option!

Yes, Rustoleum will work fine.

I've never had issues with Krylon, Rustoleum, etc. on underhood brackets, pulleys, etc. The only spots that get real hot are the crossover passage on the intake manifold, and especially the cylinder heads where the center two exhaust ports exit. Even with engine paint, those areas will eventually blister and burn. You can extend the life of the top coat in those areas by first spraying on some high temp silver paint, but it's still not a permanent fix.

Eastwood Underhood Black works great. Rostoleum #7777 leaves a very similar finish. But Rustoleum is so finicky on recoat or touchup. It often wrinkles up when recoating, even if you wait the prescribed 48 hours. Eastwood is more user-friendly.

Hard to beat the Eastwood products. Seems half the spray cans I buy at Lowe’s or the parts store have crappy nozzles

Agree on the Eastwood paint. It's more expensive, but it lays down great, covers better, and is much more durable than the Rustoleum or Krylon paints I've used the before.

Krylon semi is a dead ringer for GM semi black.

Dick mentioned Rustoleum #7777 which is satin black. Do not paint anything "flat" black regardless of the brand you choose, use satin instead when you want low gloss. Flat holds dirt where satin, semi-gloss, and gloss do not. Makes it easier to keep everything clean looking.

I agree on staying away from flat black. Never seems to look right

After a lot of research on this forum, I went with the Martin Senour line of paint from NAPA. Love the results. A bit soft, and super finicky to temperature/humidity, but it looks right IMO. Chassis Black (MS 7243) and Underhood Black (MS 7242). Rustoleum would have been easier, but I achieved the look I was going for.
