Priming and Riveting Vert Stab Spars

Today was productive, although I never get as far as I think I will during a build session. Stuff always crops up to slow me down. Today was no different. I got the spars and ribs primed uneventfully. I'd prefer doing it outdoors but the wind precluded that today so it was in the garage. I wore my respirator and was thankful not to be inhaling the primer fumes which are pretty intense. The heat gun worked great for drying between the 3 light coats and I was pleased with the results. The interior skin rivet lines were done freehand with a small 1" foam brush. Cosmetically it's not very pretty. But it seemed pointless and a huge waste of time and effort to mask off those sections in order to have neat, straight lines when its all going to be hidden. I primed directly over the cleaned alclad. I just don't see the point in scuffing the alclad for better primer adhesion at the cost of reducing the corrosion resistance of the skin. Opinions/techniques are all over the map for priming RVs on the internet. I read it all and made my choice on how I'm going to do it. I also used Q-tips to add primer in the rivet holes of the steel rudder mount brackets. That seemed prudent given aluminum rivets will be put in those holes. Priming complete I was finally able to start riveting the main and front spar. I had a couple bad rivets that I was able to drillout without too much drama. Was thankful for my flange yoke for my squeezer. That's a must have tool. Bucked most of the rivets on the front spar because they were just not accessible with the squeezer yoke. Overall I was pretty happy with my rivets today.
