One theory is to not go more than ten years without recovering.
The theory being that after that much time exposed to the elements, you
would want to strip everything off to thoroughly inspect the airframe for
corrosion.


The 10 year replacement theory is a great "perfect world" idea, but most
folks who are not named Buffet, Gates, Kennedy, etc. simply can't afford the
cost. Cover jobs are expensive. Real expensive. As in 4 years of college
tuition expensive, or downpayment on a small house expensive. Since the
sky isn't raining old rag wings, the 15-20 year re-cover cycle appears to be
adequate...

There is no life limit on the new fabric material. UV is its only
weakness.
If the dope or paint has been put on properly, it will last as long as
the coatings last.
The coatings can get re-vitalized from time to time to keep them
plyable.
There is no reason why fabric can't last 20,30-40+ years if you don't
let the sun get to the fabric.

Like any airplane, the structure needs to be inspected whether it has
fabric or aluminum for covering.
