Expose all of the dry parts and either spray them with Fix +. If you don't have Fix + mix 3 parts water with 1 part glycerin (available at the drugstore) and get the shadestick wet, but not sopping. Then wrap the shadestick loosely with plastic to retain the moisture, and leave it for a day or so. This is the only thing that I can think of that could fix it; I hope it works; good luck!
