    This is a chrome Harley windshield frame piece. Trying to shoot gloss black over it..all the normal prep…clean, scuff, pre blow dry, powder. The coating looks nice and even going in the oven, when it’s done I get wavy lines or run lines. Clean off pc, soak with pre, dry and shoot again…same thing. So the third time 😡 , substrate shows thru…okay more powder, I’ll try shooting warm @ 160. Looks good, put it in the oven, 5 minutes later I’ve got a “perfect” black wrinkle 😮 ! The last 2 pieces just won’t take the powder…ideas?? Bob
