Update: I found the interior touch up paint which I used on one of the seats spots and which matched up very well with the color of the seat, even close up it's undetectable. It's from Colourblock ( the exterior paint I have is from Touchupdirect ) . Anyway, I put a very small amount of it in the corner of the windowsill's rubbed off area and unfortunately it stands out like a sore thumb; too flat and shiny vs. the grainy and duller rest of the sill. So that's definitely not going to work unless I use the grain restoration pattern from leatherworldtech, mentioned in the previous posts.
I can probably find a shop who can do the grain restoration for me, but the more I think about that my arm & elbow is on that sill 99% of the time I drive, I'm really leaning toward having those segments painted dark blue to match my dashboard color . Functionally, dark blue is not going to show the dirt so easily, and aesthetically I actually like the idea of having a two tone "accent" there.
I can visualize it, but wish I had the software and was able to photoshop it so I can get a better image of what the overall interior would look like with those doors segments colored that way..
