Post up your cheap paint jobs!

A acrylic enamel with a catalyst, holds up well here. That Rustoleum is a slow flowing oil base,I wouldn't trust it to engine block heat.

I painted mine with Rustoleum Industrial Red (from a quart can, thinned, HVLP gun, over SEM etch primer).

It is holding up very well except on the intake, in the exhaust crossover area. I do not have my exhaust crossover blocked.
