I`m new to powdercoating . I just did a air cleaner with louvers in the side of it . I`m still learning how to get the right Thickens and to make sure I cover the hole thing . My question is can I recoat the piece or do i have to strip it . To redo it . I used a flat black PC . It also has these little pits in it . If I can re shoot it should I lightly sand the pits and then recoat it ?I hope some one can help me .
