More specifically, how do guys with short arms paint metalics on roofs? It's not a height issue, as I have made two 20" tall x 6' platforms. My problem is my arms are not long enough to hold the spraygun in the proper perpendicular position to get a good even spray pattern at the center of the roof. I can get it close enough with the primers and clearcoats, but the base coat metalic is giving me fits! I can't be the only one who has this problem. Yeah, I know, I should let the pros do it, but I've always been proud of the fact I've been able to say I built the car 100% myself. We had a thread going a few months ago on tools WE WISHED were available. lol, I need a paint gun extension! frustrated DIY'r gettin' ready for another try.
