Just when you thought this topic was totally exhausted, I've found a new product for the cladding. I was experiencing some fading and light scratching in the cladding, and was getting tired of the effort it took to use the gel cleaners. Besides, some of the color fading was evident despite these efforts. I tried a product by Autoglym, called "Bumper Black" which is a spray and it renewed the cladding beautifully. All scratches and discolorations just aren't easily seen at all. I sprayed the stuff onto a soft microfiber sponge and then applied it , so it was relatively painless and quick.
Here's the link for anyone interested.
