sorry!
OK, update...
meanwhile I removed wing covering completely. Collect each single piece in a waste bag to check the weight. Unbelievable amount of car paint not sticking to the poly-fiber...All trash!
I found some unglued false ribs, a leaking tank which contaminated ribs with 2stroke mix and came off parts of alloy end. I think this is also the reason for the wrinkles, I described in my previous thread. As flaperon brackets were removed by previous owner and put back in place on covered wing, riveting was incomplete and also only into wood capstrip. Alloy strips were no more in place...
By the way I built a wing rig. Due to my bicycle profession I decided to use 2 workstands, some tube crap wrapped with handlebar tape. Bolt together with wodden angles. Nice adjustable and quick solution...
