Sand blast gun

Glass bead is the best in my cabinet. Its an industrial one i found on the buy and sell.
I upgraded the gun,made a world of difference. I use mine often.
My cabinet exhausts through wall,outside.

Biggest issue i had when it would block, the stop ring on the ceramic tip needed to be adjusted.increased the gap slightly and it doesent block any more.
The more money you spend on the gun,the less air you need.
