Washed, scotchbrited, etched, and primed all the rear spar parts. I'm getting better at applying the AFS primer. As long as I set up correctly and take my time, it's turning out pretty nice. I applied it today with a litlle more air pressure than I had been using, and it seemed to aid in getting a nice even, smoother finish. On the down side, you use up the product faster...I almost ran out before getting all the parts done.
