Trimmed and smoothed the outer edge of the wing fairing. I will roll the outer edge ever so slightly to press down when screwed in. The side that meets the fuselage and holds the rubber seal was trimmed to be 1/8 inch away from fuselage skin. Because the fuselage skin can move inwards between bulkheads, I edged the fairing to stay 1/8 away from the innermost push of the fuselage skin. In a couple places that appears as a slight indentation, but when I test fitted the seal, you cannot really see it. However, I am prepared to file that fairing edge straight if necessary.
