I've been using Smoke's clear with the dry tumble method to coat my 9mm boolits. Yesterday I did 900 (in batches of 100), and I realized something that seems like it should have been obvious from the start. I always wipe the boolit base, and set them on parchment paper with ammo trays. I end up having to change paper fairly often or I'll get paint caked on the bases. Well, Eureka! Now before I put the tray in the oven, I blow the tray off. I make sure not to breath back in as I do this. This completely removes spilled powder between the boolits. Furthermore, if a coating of paint is extra thick, I can simply blow the rack of boolits a few extra seconds and thin the coating out to whatever looks correct. This epiphany may be something everybody else has already figured out, but if not give it a try. No need for PID's attached to fans or regulated compressors, just use them lungs!
