would automotive paint be able to hold up on engine components? i wanting to paint my turbo compressor housing, valve covers, alternator bracket, intake and intercooler pipeing the same color as the truck. but what im wonding is if the paint will hold up on the engine parts?

 

Regular automotive paint will not hold up to the high temps you're looking at. There is some high temp paint made by VHT that you can get in a rattle-can, but the color selection is somewhat limited.

VHT Engine Enamel™

 

oh darn i have extra metallic silver left over from getting the truck painted i thought i would be sweet on all the cummins engine components with a ford blue block and head

 

You might be able to get away with doing it on the intake and maybe the intercooler pipes, but I don't think it would last on much of the other stuff you mentioned.

 

I use duplicolor ceramic engine paint with great results

 

whats the best way to prep everything i used a wire wheel to get it down to bare metal the first time and it still flaked that was using the duplicolor 500* stuff

 

You need to use their high temp primer. Plus depending on what you're putting it on (exhaust manifolds, turbine part of the turbo) it might be getting too hot. If you use the VHT Flameproof Coating, it's good up to 2000*.

Also, you need to make sure the part is 100% clean before applying any paint. I use Dupont Prepsol, but I'm not sure you can get that at a parts store. I get mine from a body supply shop. Just look for something that says it will remove stuff like grease and wax.

 

I just use lacquer thinner to prep stuff. It cleans well and it dries without leaving a film or residue

 

Yeah lacquer thinner works too. The important thing is the no residue part.

 

the paint now is only on my valve covers and intake and chipping so heat isnt really an issue would powdercoating be a better choice for durability
