Brief Description: Did a few rivets on the top skins
Had a friend, Peter DiTomaso, over a few days ago and let him buck a few rivets for fun. Afterwards, I noticed a few rivet heads not quite flush. As we puzzled over the reason why, Peter came up with it; the plastic film that I had left in place was under the edges of the mushroom bucking bar, and raised it just enough to allow the flush rivet head to not seat completely. We removed the film and drove a few more, and they were fine. We hit the first ones another lick, and they seated well too.
