Ok, I am covering starting the fuselage sides. The poly fiber manual says to coat aluminum parts with 3:1 poly brush/reducer. So I did that around the door joggles. Now do you then use Poly tak to glue the fabric to the door joggles with the base coat of poly brush OR use poly brush through the fabric to attach them to the joggles? Will using poly tak against the base coat of poly brush be a strong enough bond for the shrinking? Or should I remove the base poly brush coat and attach the side fabric to the door joggles using just Poly tak? This is my first time covering so sometimes the poly manual doesn't make sense.
