Painting an engine

[burrpenick]

I'm rebuilding my 360 and its been dipped. A buddy tells me I should first spray a coat of urethane primer and then use the high heat engine paint. I like that primer and it seems to be tough, but is that what is recommended? I will not be painting the intake or valve covers, so there is really not much to cover.

Thanks, George

if the primer is not heat resilient it can lift the paint above it , I would be more inclined to use an epoxy paint , not sure what works best

Clean the bare metal with a good metal prep cleaner like DX 579. This will remove any assembly lube,minor rust and any other contaminates.
Clean it again with a good wax and grease remove like DX 330.
Then clean again with Dx 394. This will remove any organic contaminates.
Spray it with a epoxy primer like DPLF 50 with 402 catalist.
Then good to color.

This would be worth trying prior to paint. But only a light coat.

i duplicolor engine primered everything, then used their paint. Pretty happy with it. Wish i woulda polished the valve covers up a bit more. Oh then i high temp clear coated

On the T/A I used PPG epoxy primer first. Then I used PPG base/clear for the color. The paint is automotive HEMI Orange and the same for the clear. I did the same to the RR and it has over 8K miles and looks the same as the day it was installed.

I used a wire brush, then brake cleaner, then wax and grease remover to get my engine pretty clean. Then DP60 and Deltron
