Discovered the Icarex Polycarbonite coated ripstop, saw it on the TufFlight website and ordered some. Man, that stuff is slick! Spray a coat of 3m77 over the wing, wait 5 minutes for it to dry, then lay on the Icarex and iron it down. Quickest building, best looking ripstop wings I've ever done. Only drawback is the cost. 8.95/yr, but some sweet stuff to work with....
