Another question. What prep would you recommend for the rough casting? It's a brand new crate motor. I was thinking maybe a scourer disc on a drill or die grinder.

Should it be prepped within a certain amount of time of painting before it re oxidizes? I looked up the ppg product and it says to wipe down with 50/50 metho and water bofore coating. Is this to remove oxide or just clean oils.

Appreciate your help. My paint supplier has all the stuff but not the expertise. They sold me the wrong hardner with my clear and it gave me all sorts of solvent pop issues. They told me air was getting trapped and causing the pin holes.
