plastic fender molding turning blue

i have a 98 jeep wrangler and the plastic side fenders are turning blue, ive tried armor all to turn it back to black, but it didnt really work. is there a better product to use? or are they just perminatly messed up?

Had the same prob with my 97, the plastic fades in those years. There is a product that you can get, forget the name (wish I could), but it only blackens the flares for about 3-4 months. I've heard of some guys painting them.
