The closest I've gotten to a touch up for the console looks like the touch up paint for my light silver 2008 exterior paint. It is a gloss so flat would be better. Anyone find a good touchup match for the silver? Ron

 

I do not think there is a proper paint code for the interior silver (that has been found) could be wrong though.

He used Duplicolor Charcoal Silver and it looks like a pretty good match (was spray obviously not a touch up, but I assume they would have the same color in multiple styles)

 

I have used a spray, on a piece of cardboard, as an artists' palette. Dip your little brush in the puddle you make on the cardboard.

Works in a pinch! And is better than nothing.
