Ceconite Wings Question

Hello. I'm considering purchasing a plane that has Ceconite wings.
They were recovered last year professionally, and according to an A&P
I asked to have a quick look, were done well and correctly, and have a
UV protectant. My question is the following: I don't have access to a
hanger. This plane would be exposed to the elements in the Midwest.
How long could I expect to fly this plane before the Ceconite would
need replacement? Is there an average 'lifespan' for this type of wing
covering if exposed to the elements?

Thanks,

Cap
