Which product to use for external rubber?

[BMW^Z4]

External window rubber started getting grey on my X3 and it does not look good. Which product do you reccomend me to make it black again and protect it. I used AG but does not last long...

If you are talking about what I think you are 1Z Einszett Rubber Care Stick Gummi Pflege” works great.

I always use 303 Protectant on all window and door rubber.

I think both of those recommended look nice but they both wash off and down the side of my car when it rains. I prefer Duragloss Rubber and Flat Black Dressing. It is water resistant and won't wash off if it is given time to cure. If the damage is bad enough and cannot be covered up then I have used acetone to remove a thin layer of rubber. But you have to be very careful because it will ruin your paint if it touches it.

I only use 303 for interior plastic because it seems to do a good job of protecting the plastic from the sun beating through the window. And I use the Gummi Pledge on the inside door seals where water cannot get.

I love the Einszett Rubber Stick and highly suggest it.
