I built 3 sets of "spats", the fairing that transitions from the wheel pant to the gear leg. The first was very stiff and intended to remain on the gear leg. I decided that was too heavy and that I wanted a removable piece. The next build was two layers of BID in multiple pieces and proved to be the most complex layup I have yet done. When sanding and smoothing the result I determined that I need more strength at the attach points, and did a 3rd build. This one had tapes around the perimeter and a better job of smoothing the surfaces.
I bought another gallon of West 105 resin and quart of 206 slow hardener, 15 yards of 7 oz cloth and 50 yards of 3" tape.
