When painting the engine, do I Primer it first? I have the Hi-temp paint - and the Pre-paint cleaner... Just havent found anything related to prepping the engine....

My major thought to why the answer is no - I have not found any "Hi-Temp" primer... Just thought I'd check here with all the knowledge..

I have never put primer on mine for the reason you mention.

There is high temp primer out there, and clear coat. I forget the name of the vendor, it's not VHT. I got all mine at Checkers.

I saw a Clear Hi Temp paint the other day at WalMart. Its made by plasti Kote. Its in the same looking cans as their other hi temp paints. I was thinking why in the world would they make clear hi temp paint but now i see why. Is it necessary to put a clear coat on?

I hear it's all about the prep. I guess if you do a good prep job, just about anything will stick, huh..

i sorta want to clear stuff up on that. If you are going to the paint store and asking for paint to paint a motor, they are giving you an acrylic enamel most likely, not a regular paint for a car. Most cars (with exceptions) are base coat/ clear coat paints. They will fade/crack due to block heat after a year or so...maybe 3 if you are lucky. If you use an enamel based paint it should last a long time.

Most paint supply store can mix it in an aresol (sp?) can for you if you dont have a paint sprayer and compressor

I just use a coat or two of high-temp engine enamel after making sure the block is as oil-free as possible. I only bother to paint the engine if I'm pulling it out.

On the exhaust I have had pretty good success with the high temp coatings from Eastwood. For the price this stuff is very good.

That's true. I really don't know why everyone thinks their engine gets so hot that normal paint of any kind won't work. Except for the exhaust port area of cast iron heads, the rest of the block and heads stay fairly cool. If your water temp is 180-200 or so, you gotta figure the metal it's cooling (i.e.-the block) is pretty close, right? BC/CC paint will work just fine for likely as long as the motor, but then again I've had motors that only lasted for a year...

I have used the "Stainless Coating" but the shade of grey makes it look dirty to me.I wish it was more of a "jet hot" color

I went a wee bit different route on my paint. I first brushed on Zero Rust and then topcoated with the spray bomb Ford Blue. It has stuck better than just using the spray bombs. I don't have a chip or flake anywhere on the motor, including around the exhaust ports on my stock heads. I have some discoloration at the front of the motor at the edge of the intake manifold but that was from leaking coolant. I also see that POR15 has engine paint but i've heard bad things about the color not matching.

I just put the black on the Coupe exhaust manifolds and it is holding up very well.

I painted my manifolds with POR15 high temp header paint and it is still holding strong. It's pretty hard to get the manifolds clean with the pitting they normally have, plus i don't have a sandblaster. Surface prep wasn't the best but they are still holding after 8k miles.

Isn't it amazing how well some of the current exhaust paints work? I use Eastwood's stuff on cast manifolds, and brush it on freshly blasted manifolds and it held up since '96 on my wife's Corvette. I remember the old days of painting headers with VHT (I always had a thing for white headers) and it would last about a day or so before flaking off. My current headers are ceramic coated and will likely outlast the motor.
