Prepped to rivet aileron gap fairing onto the right wing. Since the area behind the gap seal won’t be accessible and will be subject to the elements, I scuffed, cleaned with dawn soap, wiped with MEK and shot a coat of primer on the spar and skin. As soon as I sprayed the primer on, I clecoed the gap seal to the spar and top skin. Squeezed all of the AN470AD-4’s and got a few of the -5’s done.
