that's one of them areas that i have tired in the past but haven't found anything that lasts very long and doesn't leave residue behind. Looks good when you first apply it until you touch it. I have used back to black in the past on the girlfriends punto black bumpers and looked good.

Being a Meg's man i would give there Natural Shine Vinyl and Rubber Protectant a go as with all there other products are top notch.

I have used Silicon lub spray in the past and comes up good, but as most don't last.
I always thought that the door surrounds are a bit of a let down when you see cars with proper colour coded solid door surrounds.

I don't think there are many products about that offer a non shiny finish other than giving them a good clean down
