I have a pannier bag that was left sitting in the sun for a very, very long time and has faded from it's original black colour to a splotchy grey colour. Other than looking rather crappy, the panniers are in pretty good shape but I'd like to have the bag look a bit better. Has anyone had any luck using a dye on panniers to revive the colour? If so, how did you go about it?
The fabric appears to be nylon like that used to make backpacks.
