I used the duplicolor stuff and it turned out okay, not perfect but that's okay, it is what it is. Has held up pretty well daily driving and autocross. The only thing that I'll say about it that's kind of bad is that it's nearly impossible to get all the brake dust back out of, the color seems to "fade" a little. Did mine about a year ago and I'm going to assume a touch-up will bring it back to the bright red.
On the up-side, I think I paid something like $15 at AutoZone with a coupon or something.
Oh, I did forget to add that it's very thick and self levels which is pretty nice.
