Usual motorway chip marks but also a scratch on the color-coded front right corner bumper - scuffed wall.

Will the matching body paint for my color (Akoya Silver I think - Dark Grey), do for the plastic bumper touch up also?

Is there a number I need to get from Chassis tag or anything to make sure I get right touch-up paint?

Recommendations for where to source touchup paint? Dealer?

Thanks Guys
