I have done this work for too many decades now so I have preferences.
I despise Polylon because, over the years after it failed, I have
replaced every color imaginable with cotton rubberized cloth.

While the purple Polylon seemed to stay airtight, it takes three times
as long to cover a set of pneumatics. Just cutting the strips is slow,
and don't sneeze or have the air conditioning turn on while doing it or
your strips will end up blown all over the shop. Don't get me started
on the glues that it will stick to.

I used Polylon on several stacks in the last few years when every
supplier ran out of real rubberized cloth. I just finished recovering
all my recovered pneumatics on two of those stacks because the Polylon
refused to stick in an acceptable manner even using the prescribed glue
for use with Polylon.

I recently bought 20 or 30 yards of thin pneumatic cloth from John
Tuttle at Player-care.com and I find it to be excellent to work with and
it is totally airtight. Even though it costs more money than it used to,
it seems to be far better quality than what we have had available for
some time now.
