303 and PFDs

Advice
#1

Has anyone had any experience with 303, or any other protectant for preventing sun fading of PFDs–particularly 500 Cordura Denier Nylon?

#2

Works great on nylon straps!

#3

303 makes a fabric spray.

#4

303’s fabric spray is a DWR. It’s also the best DWR I’ve used, but there’s nothing on the label stating it offers UV protection. Their website does claim it will maintain colorfastness, so might be worth a try.

The 303 UV spray states it’s for vinyl, rubber, plastic, leather, and fiberglass.
