And I need to mention this again, for those of you worried about the plastic covered bumper, or any other plastic trim parts. Yes, these fade, oxidize, and become pretty nasty looking over time. You can make it look 90% better, by drenching after every washing with some sort of tire gloss product, Armor all, or whatever.... But IMPO, this becomes kind of a PITA after a while.
Fortunately their is a really easy, nice looking fix for this. Its called Bulldawg spray. Basically it is a special type of primer, called an adhesion promotor. It is SUPER sticky, and will stick to plastic, glass, and even chrome. Then you can spray it with the paint of your choice, or roll on bed liner, whatever you prefer.
