Paint runs? When I was restoring old cars, I would on occasion, get a run in the paint. As soon as I saw it, I put the gun down, get my 2" masking tape that I have attached to my hip, pull a piece about 10" long. Sticky side towards the run, make a loop in the tape(omega sign). Gently make contact with the tape to the middle of the run and let the tape splay out to the ends of the run. Gently reverse this by pulling slowly back. The tape will lift the run. Let it set up a minute or so then give one or two short hits from the gun. The fresher the paint, the more success you will have. Lion 8, form Southern N.J.
