Started today´s session with deburr and primer rear spar and angle. Continue with all small parts, angles and doublers. I guess I painted wrong side in some cases, but anyway this is not the last time to use primer can. After drying, I sanded rear spar and angle 6-W-11-20 and start assembel with clecos. Lot´s of riveting, I pick up the pneumatic riveter that was included in the kit, and used it for first time. Great, this tool will save some time.
