For touch up paint, I have used acrylic enamel mixed to match the AMC paint codes at my local auto body supply. From what I understand, OEM touch up paint is lacquer based. I am looking into the Langka kit that uses a special "Blob Eliminator" that allows you to simply wipe the touch up paint blob until it becomes even with the surrounding paint. I hear good things. I contacted the company and they said the blob eliminator could be used with acrylic enamel paint, but to give it a longer drying time and possibly dilute the BE 1:1 with water. That is my plan. I have a ton of chips in the strangest places and I can't imagine wet sanding them all out.
