i can really relate to these covering problems. i have a number of gp planes and have spent a lot of time geting wrinkles out. red seems to be the worst. the last one i put together, a minnow, was terrible. on the other hand my revolvers have been perfect. what i have learned is to take all the parts out of the plastic and let them sit out for a few days. this hasworked really well for me and saved me a couple of hours per plane. also, i think hobby services should reimburse the customers for shiping and ins when they have some of the issues as stated above.
