Best touch up paint?

[JumpMaster82d]

Ive got a couple small scratches around the drivers side B pillar that need to be touched up. Whats the best touch up method (delivery system) and company to buy from? The truck is Iridium Metallic if that matters.

Always had a good color match and quality from AC Delco. It's made by Duplicolor. I fill chips with the paint, the sand them with 2500 grit wet, then buff out with compound. Can't tell where they were when I get done with them.
