After the wing was mounted, I found there was a slight upward bow in the outermost portion. I agonized about it for a long time, but was fortunate enough to talk about it to Mike Bergen. Turns out he had the same condition and that it was easy to fix.
I started by marking the upper wing, then simply slit it with my Dremel. Using a hack saw blade, I scored the foam all the way through to the lower skin.
Next, I stuck a couple of tongue depressors in the slit to open it enough to take the bow out of the trailing edge. It wasn't much!
I filled the wound with TAP 30, expanding foam from Aircraft Spruce. By the way, DO NOT use the two part foam from Wicks. It is really lousy, weak and crumbly.
