Well I do know that if you wanted to fade something very quickly such as a colored T-shirt or something that has color, you can expose it to intense UV light, such as welding or plasma cutting. I deal with welding on a daily basis and know that The intense UV light will fade your clothes very rapidly and I am sure if you had someone who was willing to hang a crank bait in a welding booth at a school for welding will do a number on it! But why do you fade it, just to create a non-duplicated bait?
