Anyone keeping a fabric plane in the open?

Ok, I know the received wisdom that a fabric plane shouldn't be kept
in the open and should always be hangared.

But, I started to question this after noticing several fabric planes
in the open at my home airport. They look in better shape than the
metal winged planes sometimes. I also know that the newer fabrics
(Ceconite and others) last much longer than the old cotton. And that
UV resistants in paint help more.

Anyone really doing this? What are the results on your plane? Any
A&Ps seen results from outside fabric?

Thanks,
