We used the Testors paint pens - get both the red/white/black and gold/silver/black kits and 99% of your needs are met. Paint the area, and go back over with either some micromesh to remove the surface paint, or a MrClean Magic eraser, with light passes. The magic eraser is fine enough and firm enough to not dig out the recesses or mar the surface.
I dunno what grit our micromesh kit is - nothing is marked.
