I'm in the process of detailing the engine compartment (really just starting) . I've beadblasting the parts that I have removed so far; brackets; pullies, air cleaner housing, etc. I was planning on using either POR15 or Eastwood's Chassis Black but will these paints hold up to the heat? They say their good for up to 250 degrees F. Has anyone used these for these type of parts or should I keep with a high temp paint? I'm not planning on using this paint for the block or valve covers; I have a high temp chevy orange for that, only the ancillary parts would get the Chassis Black.

thanks

I went with hi temp gloss black, it holds up pretty good, though if I could afford it I'd get billet pulleys and powdercoat everything else.

POR15 will do a good job. It dries like powercoat.

POR-15 has a line of engine high-heat paints, check them out.

Believe it or not, almost any automotive spray paint will work under the hood as long as it isn't directly on the exhaust manifold.

One thing to consider though, is how long you want it to last. What usually goes first is the gloss. It's the constant heat cycles, exposure to chemicals etc that will break down the nice shiney finish.

Check out the paint and body forum. I actually went to a local NAPA store that has a paint department and got some urethane enamel and some epoxy primer. I just sprayed it with an old detail gun that I had. The results are awesome! I've not had it on that long and am still in the process of putting things together on my 65, but if you read about urethane enamels, the gloss will last through about anything.

Anyway, it may be a bit overboard... but if you are looking at doing it once and having it last....it might be an alternative.
