I’ve had the powdercoating system for a while. I’ve had to replace guns because I used too much pressure, I get that. My newest gun has been used to do the front suspension pieces for my son-in-law’s 67 Malibu…….and today, I was coating some outside mirror parts for my friend’s 66 C10 pickup. Got to the last piece, had the gun in my hand, pulled the trigger, and the plastic part broke off and fell down. It looks like it’s broken right where the metal meets the plastic. I don’t see any way to fix it, but is there a repair center? or, do I just buy another gun, again?
