What is it about north Texas and gliders in trailers. We picked up a Janus C from north Texas years ago. One season in the desert and the gelcoat was popping off the wings. Owner took all the old gelcoat off, it chipped off very easily, there is a video of it on YouTube. Re profiled the wings, prepped as JJ described, painted with poly and sanded to a glass finish. Looked great when he was done.
