I have had a glider that when it got below 32 it developed goose bumps all over
the wings. This was during the early 80's. The factory sent over folks to see
this after they saw the pictures. It was found that when they sprayed the gel
coat into the wing molds that mosture was present in the air compressure and
the filtering system they were using was not getting all the mosture out. They
took the glider back, and I got a brand new one. One of the few times that the
factory stood up for its product. Thermal tight, Soar high, Fly safe, # 711.
