Long story as short as possible…..Been doing some restoration work in SD Gloss Black and have noticed small white specks, not OG, not pinholes, just annoying . I thought at first items was contaminated from previously shooting SD Gloss White. Having now cleaned gun and accessories 3 times, replaced hose and powder container, I still have the same problem:confused: Thought maybe was blast media coming out at bake temperature, so i tested on an unblasted sample panel and got same results:mad: I then remembered that this batch of Black was in transit for 6 days and arrived in severely clumped condition (almost entire container) and had to use a flour sifter to get most of it to a usable state. Could this have caused the powder to go bad and cause the specks?
