Re: Engine paint question

Hmm, all of the rattle-can engine paints I've used don't require a primer and seem to flow pretty well if sprayed correctly. A simple trick that works well to boost pressure and make paint flow even better is to run hot water over the can for a bit just before spraying. The texture on the block is going to be there no matter what you do. If you are getting excessive orange peel on stuff such as the valve covers and other sheet metal, then I suggest your paint technique needs some more practice. I usually start with one very light tack coat, followed by at least two heavier wet coats.
