Mike or Kerry...
Its not too difficult to get the wax off black trim. Treat it like you treat your tires. Get a good tire dressing, like Meguiars gold class(a gel) and apply it. The trim will look signifigantly newer, and won't appear faded like it most likely does. If this dosent work(it will)... there is a product called Forever Black thats made for plastic and rubber trim pieces that will take out stains, and bring it back to new color. Good luck. ~Cody
