everything seems to have a shelf life. Even the kids seats in the back seat of my car.
I have done a little gelcoating. I patched the holes left by screws when I removed some snap fasteners around my windows one year, the holes left when I removed a pair of undersized life rings another year, chips and gouges fixed several other years.

The gelcoat I use has been opened several times over the last 15 years, but was re-closed with a hammer after every use, so very little new air has been introduced into the pint can. I used so little of it that I still have enough at that rate for another 20 years. The last time I used it, it was as good as the first time, so no, I don't think its shelf life is a problem.

I have tried the saran wrap trick to get a shiny surface. I ws never able to get it perfectly flat and smooth in filling holes, so I generally don't. Instead I use a good cutting compound for a shine and it turns out much better.
