Wood glider outdoor storage

Random question (kinda): Can an all-wood homebuilt glider be tied down outside year-round in a dry climate (e.g., Colorado) and be weather-protected by padded covers? The glider's plywood skin is covered by a layer of thin fiberglass, then painted. I guess I'm asking for actual experience or knowledge from anyone who has sucessfully done so. The glider's owner would be willing to periodically remove/dry-out/put back the covers after rain/snow/hail, etc. Being assembled and tied down is the only practical way this particular glider would be flown.
