I have had my dual voltage gun for almost two years and it has served me well.
I have not used it in 6 months and when I did, I noticed powder was spraying all over the place making a big mess. I then noticed that the blue barrel had developed a crack that wrapped around the barrel.
Eastwood says it is out of warranty and there is nothing they can do for it.
I am thinking about using my plastic welder to fix this crack.
