What do you guys use to clean, detail and preserve the black rubber trim on your bumpers?

I USE TURTLE WAX 2001 I use it on the seats and dash as well also on the vinyl interior. It is not greasy like Armor all and it give great uv protction. I have used it on the Vinyl cover for out hot tub that is exposed to the weather 24 7 and it is 4 yrs old and looks like new. It is covered with the same stuff our seats are. I find it work as well on tires to prevent checking. By the way , IS IT COLD UP THERE ?? GARY I use lacquer thinner to clean rubber.

I use a product that I bought from MSA called "Back to Black".
