Completed riveting the right seat back. Right at the end I was sweating like a pig. Its only 110 in the garage. 98% humidity. The sweat was dripping off my hands and the bucking bar slipped and I really dinged the seatback on the upper hinge line. O well. At least it gets covered up by the seat cushion. If this happens on one of the main skins you might have to call the sucicide squad.
