Did a bit more work on the trim tab to get it aerodynamically clean. I didn't get a real clean final bend of the skin and the holes were misaligned just a bit after priming. I cleaned up the countersunk holes on the upper spar flange and actually enlarged 4 of the holes. This is unfortunate cosmetically since you'll see a few -4 rivet heads mixed in with the -3's. However, shouldn't be noticeable to most.
