Deburr and primer on flap-hingle 6-W-1-4, shim 6-W-8-59, frames 6-W-9-54 and panels 6-W-9-55. Later on, sanded and clean and finally rivet them in position. Installed 12 rivnuts 914015M4, and stainless screws M4. I turned wing over again and prepare for upper skin. I found that the amount of no5 rivets will not be enough to close rest of wings and aileron/flaps. I called ICP and send a mail. Let´s see if this generates a packet with rivets. Still waiting for delivery of the missing roll-cage.
