Shooting my superhonda 850 motor soon, was gonna use the military flat black aircraft paint we usually have at work but I guess it was for an old contract and we no longer have any. Gonna have to go commercial. It's going on the jug, head and valve cover of an air colled engine, so I figure it will experience temps in the high 2's at the worst? I don't want to pull this motor, tear it down and re-prep and paint it so who has a motor that's been rockin flat black for a few years with no issues?
