Vaper primer gun has intermittent air supply
I purchased vaper 4-piece triple gun kit. used it once and 1.4 primer gun spits. 1.7 finish gun works o.k..I returned kit for free replacement & new primer gun is good for 1 use only. I thoroughly cleaned primer gun but when I tried to use it I can see bubbles coming up thru paint cup, Indicating to me that air is escaping thru cup.Repeated cleaning does not help, so I try finish gun to check air supply & it works fine. Is there repair kit for something in trigger line concerning air supply?
