I cleaned up and Deburred the rib attach angles that go on the spar. They are temporarily clecoed to the spar for safe keeping. They will be removed and primed once I have enough parts to prime. I will use P60G2 so far it has done a good job of being lite and sticking to the parts well. I have been roughing the parts up with a scotchbrite pad and washing and drying with a mild soap. I also drilled and threaded the wing tie down bolts. The plans show both sides getting threaded, I cant figure out why. But I did it anyway. I can see how it would hurt either.
