Was doing most of the painting outside,that had issues too! I blew out the garage the other day, did all my dry blockin outside, Maybe i'll rig something up when i shoot the paint, finally got my compressor back, so I can use the guns & pressures I had gotten used too, thats why I dripped the back of the trunk lid, smaller compressor, had to use the old gun, I had only shot primer through that one till that, funny it looked like it was gonin on nice, but major drippage & all in the valleys, sanding those out now, what a PITA! Rich.
