Unprotected Kevlar is susceptible to the elements. It's normally
sheathed in PVC The ends are capped and sealed to keep moisture out as
in Phillystran. It's a bit on the expensive side, but I use it to guy a
100' 45G at 3 levels. The bottom 2 are 4400# strength (1/4") with the
top being 6600 (5/16ths) with a large array on top.
I've been to the top when the wind was near my limit, yet I felt no
movement in the tower. OTOH the 30' mast out the top was moving like a
Bluegill fly rod that had just tied into a monster Bass!

What about Kevlar rope like one used in spiderbeams?
They also claim it is UV resistant and does not stretch.

Dacron has very low stretch and is available in black which is pretty UV
resistant. Nylon is pretty much like guying with rubber bands.
