Hi i have a sand blast cabinet and it has a foot pedel. You push on it sand comes out of gun. Well the gun that comes with cabinet is not doing what i need it to do. The spot sand blast gun works better. I took off the rubber front to it. I guess it works better cause it has a bigger diameter. The regular gun the metal sand blasted away where tip goes and so did the plastic spot blaster gun tip. I need a sand blast gun industrial enogh to keep up with 175 psi constant. Can anyone tell me what type gun there is out there? I been looking online and will continue too.
