I probably went through 15-20 nitrile gloves. The wet proseal cleans up very nicely with MEK. You end up tearing your gloves when wiping across edges and other open dimples with the clean up cloths. They seem to tear very easily. I liked the air pressure at 40lbs to set the rivets. The pressure guage would be at 80lbs when the gun was idled. When I was riveting with it, the pressure dropped and held at 40lbs. So far I am happy with the flush heads. They seem to sit nearly exactly flush and only a couple are ever so lightly proud and I will decide later if I will just leave them or shave them down a little.
