303 and PFDs

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

Works great on nylon straps!

303 makes a fabric spray.

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.
