This is dedicated to those of you who have lint and other crap in your powder after curing. I had this same issue for the longest time. Now it’s gone. I have made only 1 change. I rebuilt my powder booth and increased the filter and fan sizes. I now how a cross draft created by the fan that apparently keeps lint and other trash off of my parts. At first I thought my powder was contaminated but now I know it was the filtration in the powder booth that was the culprit. Anyway, take it for what you paid for it. Hope it helps others.
