[TowerTalk] aircraft bearing

[doc]

Didn't know to what you referred so did a search:
http://www.ticona.com/index/products/uhmw-pe.htm

This site does not mention outdoor use where degradation
from intense and sustained sunlight destroys many synthetics.

WDYT about UHMW bearing up under west central Florida weather?

Where does one acquire chunks of UHMW?

Just wondering ... doc
