Kurt, it may be hard to purchase the tartan paint off the shelf. This is what I do when I need some touch up paint. Just go to an automotive paint dealer/supplier (a store/vendor that supplies stuff to auto body shops) and they'll match your paint using a laser thing and mix the paint that's perfect for your color.
I did it on my GT6 and my Midget. One body shop did it for me free of charge, they had the correct color mix for glacier white.
You'll get a small bottle or rattle can that will last a long time. Worth the effort.
I'm pretty bad about scratching and small scuffs, this really comes in handy.
Good luck, let us know! :thumbsup:
