Aileron support bracket and starboard cowbell stuck in place. When bonding to composite, need to sand off gelcoat to achieve best bonding. When bonding fiberglass to metal, first layer of glass gets Redux/Peelply, then subsequent layers of Aeropoxy. Cowbell on our accelerated CPM cracked off after a few test fittings, it is stuck in place pretty good now compared to before. Y8-10-15
