Primed those aileron countersinks – what a mess. That galvanized water pipe has some sort of coating that even MEK won’t cut cut throught at first. The first application of primer didn’t go so well, so I cleaned ’em off and re-shot. What fun. The little patches of masking tape cover the countersunk holes and were supposed to keep primer from gooshing out when poured into the pipe. That didn’t work as well as I hoped.

After that, I clecoed the countersinks in the leading edges and assembled the left aileron for final riveting. Sorry, no pictures of the assembled aileron.
