I've been using the PPS for several years with great success. I'm wondering if anyone regularly saves finish in the cup with a plug inserted to reuse at a later date? Doesn't the finish congeal in the lid screen? How do you mix it up before spraying? I spray nitrocellulose lacquer, shellac and polyurethane, and lately I've been doing touch-ups and smaller jobs, and I use a fresh cup and lid every time because I can't risk spraying bad finish. But the cost is adding up. Any suggestions?
Thank you!
