While taking apart the rear spar/bottom skin rivets, I noticed a small (2"x2"ish) section of the skin between one rib and the spar that I failed to remove the plastic coating on the skin before riveting it to the rear spar. What would be the effect of leaving the coating on a skin and riveting it on? Would having the plastic sandwiched in the middle of the joint significantly weaken it?
I'm not planning on doing this, just curious.
