I need to repaint my air filter housing and I want to paint my master cylinder. I may also touch up radiator and engine bay wheel wells. I want to use a flat black and was wondering about any suggestions for the paint. Will high heat Rustoleum primer and paint be a good choice? This is not a show truck, this is my driver a couple times a week, in nice weather, so do not need any fancy ceramic, high priced, shiny paint.
Thanks

I used rustoleum 2x semi gloss, I like the semi gloss a lot more. The flats always get chalky and looks bad after a while, the semi gloss looks better anyways.

I suggest you don’t use Flat paint, use Matte or Satin finish.

I just resprayed under my hood with semi-gloss. Trust me it will look better than flat paint. I only used high temp paint on the radiator and the rest just Rust-Oleum semi-gloss.

I used Dupli-Color Semi-gloss black engine paint # DE1635. I like the way it lays down. Less texture with these crappy spray paints now. These pictures are 3 years after painting. The core support and radiator cover are powder coated. The rest is a can.

Typically you don't want to use high heat black on any parts that don't actually get very hot. Sure the inside of your engine bay isn't exactly cold, but it does not reach the temps that paint is designed for. High temp paint actually needs to get hot to properly cure (like a few hundred degrees kind of hot), the parts you're talking about painting get warm at times sure, but that paint is more for like if you wanted to repaint a barbecue grill or something. Regular paint will hold up just fine for what you want to paint. And I agree with everyone else on here, semi gloss or satin will look so much better than true flat black.

When I painted underparts with touch-up sprayer not rattlecan, I mixed "Flat and Semigloss" 50/50.
Good "new look" without need of Sunglasses.

Just an FYI for everybody correctly advising against "flat" sheen paint:

All paints are, by their nature, glossy. Anything less shiny than gloss has has flatteners added to it (things like talc, although there are better flattening agents now).

One practical consequence of this is when using a clearcoat. If you want a satin or matte finish and are doing multiple coats, do your first coats in gloss, and only spray the final coat with the desired sheen. Otherwise your clearcoat will come out chalky, dirty muddy and dull.

Just some expert advice from years of wood finishing.

Pick a bright color so you can see what is going on.

That dupli-color paint does lay down nice and smooth. Great spray applicator and product.
