Sanded a nick out of the outboard aileron bracket and re-primed. Primed around the mounting holes in the rear spar web in preparation for riveting of the aileron hinge brackets.
(Some people ask me why I go to the trouble to prime so extensively. I feel that anytime bare aluminum has been exposed -- in this case by drilling and countersinking holes in the bracket and/or spar web, these areas should be primed to prevent future corrosion. I especially think priming is important in locations where the plane will be painted and directly exposed to the weather later. Call me a perfectionist -- it just feels right to do it.)
