Depends on the fabric. Cotton will last 2 to 5 years tied down, but I know of a
J-3 that's been hangared for 30 years and counting with the same skin. Ceconite
or Polyfiber is advertised as having an unlimited life expectancy if properly
applied, but most manufacturers or installers recommend that the fabric be
removed every 15 years to check for corrosion in the frame. Nobody I know
actually does this.

There also used to be something called "Razorback", but I have no experience
with it.

It makes you shoot at your landlord. And it makes you miss him.
