Don’t have a hangar, so planning on tying down the glider, a standard cirrus, during the weekend. Has any one done this consistently. How bad did the gel coat deteriorate; any tips?

Some of the methods described here are fair-weather tie downs, at best. If you value your glider, come up with a system that can survive an unexpected storm (50+ kt winds). I made a pair of wing cuffs out of 3/4 exterior plywood that was doubled up to 1.5". You will have to transfer the wing profile to the wood by cardboard templates. I hot-glued strips of felt to the wood.. This project will take a full weekend (unless you've done it before, then maybe a day). I have used these for several years successfully at Nevada airports that get strong thunderstorms. They can go on over wing covers, or without.
