Query: Nice utility sprayer.

Works great if you know how to spray. Not necessarily for beginners. Only issue is with the cork gasket ring - too hard to get replacements. I spray mostly polyurethane and it normally contaminates the gasket enough that I need to replace it regularly. Wish you could get the rings by themselves in quantities of 10 or so.As with any sprayer, CLEAN IT WELL AND QUICKLY! Can't stress that enough.
