In this video of the Alaska Airmen 2016 Super Cub Raffle Plane: 1. Applying Poly-Brush, which acts as a sealer for the Poly-Fiber materials. 2. Applying reinforcing tapes and rib-stitching with Poly Fiber thread. This secures the Poly Fiber fabric to the wing. 3. Applying ‘finishing tapes’ to give the wing a tidy appearance, and produce a smooth painting surface.
