AeroPoxy`s holding strength to composites such as fiberglass and carbon fiber is due to its formulation and long cure time. We have learned to schedule major gluing sessions at day`s end to allow an overnight set. You can tack glue with Zap-a-Gap and apply AeroPoxy when you have time to set the assembly aside. It is still best to glue molded nylon \(carbon or glass filled\) parts such as hatch latches or door hinges to fiberglass with Zap-a-Gap and then apply AeroPoxy to the perimeter of the part to form a mechanical "trap."
