black chrome problems
I have a sportster air cleaner cover I am coating in black chrome with a super chrome undercoat. I spray out the undercoat and it looks great. then i spray out the black chrome and the color is great but there are spots in the black chrome. They look like the powder just pulled away from the areas. I coated the parts twice with the same results. I have cleaned the part with purple power and water and then cleaned with acetone. The spray scheduel went chrome base sprayed, part at room temp, cooked at 400 for 7 min, air cooled to 154, sprayed black chrome, goes on fine all coated, cooked at 410 for 15 minutes. pulled out and there are the spots. pics attached.....
