I had someone drive with me and while getting out; he grazed the cubbyhole with his shoe buckle (Do not ask how?). Now I have a graze mark on it, which is lighter than the original color. What can I put on it to blend it back in?

I'm not sure what kind of plastic they used on the IS's interior, but it marks easier than any I've seen before. Especially the dashboard.

I guess that I would try some ArmorAll/protectant type stuff, and see if that does anything.

Armor All is going to make the plastic shiny and greasy, and there are reports that long-term use of that product will lead to cracking and deterioration of the plastic.

I'm not sure if the product will help the damage, but even if it does, this may be a case of the cure being worse than the disease.

I've heard that too, but I have to think that it would take a lot of ArmorAll, a lot of sitting out in the temperature extremes, and a lot of years to do the damage. To hide or remove a scuff mark, I can't imagine any ill-effects.

that sucks..armor all definitely messes up dashes in the long run. It totally cracked the dash in my E320. I stop using it. Invest in a nice duster and microfiber cloth. Shiny & Greasy Armor All = Bad
