I start to install some rivets i middle of wing, but the outer part of skin seems to grow. I decided to lay down the wing again on the work bench, to easier judge straightness. Removed rivets and strap the noseskin with some 22x45 mm wooden beams under, to retain a straight skin. This works better and I carefully start rivet again. Finally I start mounting fuel door, hingle and Dzus lock. I am out of primer right now so final installation have to wait a couple days. I got a feeling that holes i main spar, upper skin and noseskin are not drilled exactly in same position. I have to use the 4 mm drillbit to clear every hole before riveting. There will be some vacuum cleaner work, inside wing.
