Hand Sprayer

I kind of like the one I use. It is modified so that instead of pump pump pumping it I just pressurise with the handy dandy blow hard (Air Compressor) Thius one blows off at 45 PSI Which I think is a bit low myself but . Well, that might be handy with the mod I did.

Drill hole, Thread valve stem into hole and apply stem nut (I used a metal valve stem that bolts in.. It is a "Custom Shop" type product for flash not pressure).
