Here's a couple a things I have picked up. 1) Put masking tap on the end of the rivet gun to help hold the gun more stable and avoid abrasion to the finished surface. Especially - flush, but works on universal as well. 2) Turn the pressure down on those little 3/32 rivets, you don't need 90psi to drive them, you'll just tear things up. MORE TO BE ADDED LATER
