has anyone on here used the new duplicolor scratch touch up kit?

 

Yep. On silver it looks like crap, but better than primer. Granted, I have flake in my paint and you don't, but it still looks bad. I've also tried the FoMoCo touch up pens--same story.

You may have better luck with yours, but I think you may be best off getting a rattle can or a pro.
