I'm just not happy with the way the wing tips fits. I spend some time filling up the gap with fiberglass, after letting it dry, i used some bondo, sanded it, and primed the corner, and then sanded again down to 900 grit. Most have fitted the tip a dozen times before I was finally happy. Took few day, and lots of hours but work out well at the end. Did the same thing to the right wing.
