Engine Paint

epoxy primer is the only thing I will ever use... I highly recommend it.

and u-tech 3.8 hi solids urethane paint for topcoat, its flexable, for heat and expansion, and I have painted 3 engines with it, over 1-2 years ago now and none have had a crack, chip or peel, even using brake clean to remove drips.

I had a fire on my motor that I sprayed and brake cleen removed all the soot, and i scraped away the melted plug wires and cleaned it... low and behold the paint sttod up to that... you cant beat it!
