I wanted to spray the frame on my GMC pick-up and was looking for how my regular full size spray gun can be changed to pressure feed. Thought this way I could spray in all directions , maybe ? Anyway I came across someone who added and extension to his touch-up gun . I looked at mine and it was made the same , what I did ,,unscrew the gun from the cup and add a vacuum hose with the proper pipe fittings . It worked great ! I could turn the gun in any direction with one hand and just hold the cup as close as possible to vertical . About a foot lower and it didn't want to siphon but I was spraying Rustoleum and maybe if thinned a little more it might not have had any problems .No way could I have gotten around the exhaust and driveshafts using it upside down with a full size gun or even the touch-up gun with the cup attached . Went I painted my Ford tractor there were times I couldn't get under and behind to paint but this would have gotten those areas and then I could have used the bigger gun on the wide open parts . The only drawback would be the small cup size , it was a pita climbing out so may times to fill
