Talked to Ken at Van's about the extra countersinking in the rear spar end doubler plates. He did not see any problems with that, and said to press on. Pretty much the same thoughts that I had...So I pressed on and primed the rear spar doublers. Didn't do the rear spar since it looked like rain... didn't rain, should have primed the rear spars as well. Oh, well... something to do tomorrow!
