Thanks for the reminder, I meant to post a reply here earlier. I did use that 160 Dark Slate in a couple of my Chryslers.

It works perfectly for touch-ups, and you can actually go all the way and cover a bolster completely. The match is dead on for this. I have one bolster in my 300m seriously worn in some spots -- there were light cracks in the leather there when I bought the car new that I should have had fixed under warranty but stupidly didn't -- and the spray perfectly covered this spot. For the Crossfire, since the marks were much smaller, I just sprayed the paint/dye on a cloth and massaged it carefully into the little wear marks. I also used an art brush. Then after drying, I did the seats with Meguiar's Gold. Presto! The marks vanished. I wish I'd taken before and after pics, but I got right into doing the job when I got the paint home and forgot.

So I'm pretty happy. Only one big warning -- this stuff dries really, really fast. I made some mistakes with the 300m the first pass and had to clean the seats off and go over everything again. You really have to use it with quick passes and very thin coats, as the leather is of course very smooth and you can easily wind up with drip marks that can be hard to get off if it dries. Use quick, thin coats, though, and the paint/dye blends into the seat perfectly.

Also, this stuff seems incredibly durable, given the scrubbing I had to do to get it off the 300m seat where I screwed up the first application.
