I use paving paint, its clear and you tint it to the desired colour $30 a litre (quart), thick and very durable, I add some enamel hardener as well makes it super tough, thin slightly to spray though a standard gun, and get at least 5 engines painted , a litre is damn close to a quart. No primer required just a thorough clean.
I did a test for color on another group. Bill Hirsch paint is almost a perfect match . Plus they say its good for 700 degrees . Closest second was the Krylon 2114 that seems to be unavailable these days and is only rated to 500 degrees
I epoxy primer the oil pan then painted with straight enamel hardener mixed in the Hirsch enamel . But the Block just paint no prime no hardener. So it retains the heat better
GSX4554ever We have a saying in paint world . A spray out card will set you free. It’s funny when guys at work paint a car and there is 7-8 variant’s for the same color. They will unmask the car. With out doing spray outs. Hilarious
You must at least prime the aluminum water pump and timing cover or the paint will peel off. I never used primer on any cast iron engine parts and never had a problem. It may still burn off the heads near exhaust manifolds and heat cross overs on intake .
Hey scubasteve455... can you share the Bill Hirsch paint part # with us? I'm looking to repaint my engine in my 69 GS400 and having problems finding the paint... Thanks...
I saw that, but saw no part #. I actually JUST saw to the left there is a description... I'm good to go. Thanks a bunch... Mike
