This is a bit unusual, but . . .

I had a set of moderately large windchimes strung with some cheap braided nylon (?) line.   After about 2 months hanging in 1/2 sun, 1/2 shade, they came crashing down in almost no wind this afternoon.   

I have some bulk 90# spectra, (only about 12 ft. and left over from an airfoil construction project) and was thinking about using it to restring the chimes.  Does anyone know how UV-resistant spectra is? Am I wasting my time and spectra?   Yes, our flight lines get plenty of sun, but they spend most of their time indoors. 

If not spectra, is there some other more UV-resistant line/cord you'd recommend?

Thanks in advance

according to google, it should work fine.

Much better then the alternatives, any natural fiber has to deal with water & molds, I know it's better then Kevlar, and I would guess that it's better then Dacron. Hit it with a little 303 protectant or another UV shield protectant for automotive/boat use, won't hurt the Spectra and will add some extra protection.
