Completed all edge, debur, dimpling of all right wings skins. fit and drilled NACA vent for riveting. Primed all wing skins with epoxy primer. Counter sunk all holes in WING spar and rear spar IAW instructions. Primed main wing spar with epoxy primer.
The instructions call for removing the blue vinyl protective coating prior to dimpling. I found leaving it on is better as it emliminates the scratches that occur with sliding the skin over the male die. It is not difficult to remove the vinyl after doing this as the instructions suggest.
I've also found that placing a piece of masking tape of the head of a flush rivet help to keep from marring the surface and actually allows the rivet gun to stay centered without slipping as easily.
