hello, i’m just wondering if there’s a simple fix for my hot coat gun. it’s leaking powder out the back where the cup screws onto. I’m not able to take the time to send it back and wait for a replacement gun so i’m just looking for a simple way i could fix this. also i’ve been looking at the performance deflectors and fluidizers for the hotcoat gun…i know this is going to sound dumb but will those parts fit any of the hot coat system guns? such as my dual voltage one.
