When I built the center spar I primed it with Zinc Phosphate but I was not real thrilled with the primer AND it was pretty expensive. I‘m sure that I applied it too heavy but it’s still not cheap. On this spar I went back to using Cortec thinned with water as I did with the tail sections. Not wanting to start a high wing vs. low wing type argument but I will stick with the Cortec from now on, I am much happier with it. I riveted this spar completely with the “C” frame riveter I made glad that I did not have to buck any more rivets. I am not sure that I could build something like a Van’s aircraft.
