I recently bought an '05 explorer XLS. The XLS has naked black plastic bumpers and wheel well trim, as well as roof racks and door edge guards. I have been using Meg's exterior trim detailer, and have noticed that it doesn't last very long either. I'm applying it with a sponge, and wiping down with MF. Within a week it has lost all it's shine, and doesn't look all that hot. The car is black, and I really, really don't want that plastic to fade to that gray color. The car is NOT garaged, as the fiance's lexus and my sea-doo occupy that space.
I would greatly appreciate some advice here.
Thanks
