Thread: engine block two stage paint?

Rattle cans will never give you a showcar or even really good finish. They may lok good for a very short time, but then they will start fading, etc.

Years ago I read an article in Street Rodder Magazine (I think) entitled "How the Pros paint an engine" or something to that effect. The secret was that the Pros used Urethane primer then top coated it with regular enamel, just like you would paint your car with. And, you could color match your car.

So 15 years ago, I ground the engine in my '27 roadster very smooth, primed it with Duponts Uroprime system, and then top coated it with Dupont Centari, to which I added hardner. The shine and gloss was just like a car body, and when I tore the engine down just last fall, it was still looking pretty good. And this is after 7 years of almost daily driving in rain and hot sun.

Just recently we painted my Son's 455 Olds with a similar system, but he wanted an old timey look, so we only ground the block slightly. He wanted the pores to show. The engine came out really good, and will be a cinch to keep clean, as dirt and grease wipe right off.

Here is a picture of his engine. We used a touch up gun to shoot both engines.
