Any advantage of using matte black on air filter assembly, radiator support, etc or my restoration projects? Is the matte black blacker then spi epoxy black? I'm thinking a few good coats 1:1 of black epoxy, what have you guys been using? Would engine bay heat cycles make the epoxy chalk or break down over the years? I have seen the epoxy fade on exterior rims, but of course they were exposed to UV light. What's everyone using and how long is it lasting? thanks guys!

A guy I know here in Canada sprayed his wheels with black epoxy 2 years ago and they're still holding up great. He washes his jeep and whatever comes off must be break dust that doesn't even bite into the epoxy.

Engine bay on your own ride?, SPI matte black will look nicer than epoxy.

I don't think the heat cycles will touch the epoxy whatsoever, but have never done it on my own cars.
 
Either one would work fine, i would use epoxy for simple reason, way stronger than the matte.
 
Is the matte black "blacker" than the epoxy? Does it go on smoother, I never sprayed it, and how's the durability?
 
I think the Matte Black is great if a flatter finish than epoxy is desired. It's very easy to spray and dries to a consistent flat sheen. There are tricks to getting the epoxy to dry flatter, but to me it's hard to do that consistently from batch to batch. The Matte Black does not have that problem, parts from one batch will match parts from another batch.
 
Thanks Crashtech, how durable is the matte black? I want a satin sheen, like you'd see on late 60's GM cars under the hood.
 
Epoxy is the most durable, of course. but if you lay epoxy down as a sealer the night before, I think the matte black is fairly tough. Epoxy should still be used on frames and suspension, imo, but for underhood, the matte is pretty nice. it is probably flatter than original, though.
