Dr.Colorchip matches your factory paint. It works best on smaller chip's the size of a sesame seed or smaller. It's a no-brainer system because you just glob some paint on the spot and wipe away the surrounding area with the solution it comes with after a few minutes. It's finicky on larger chips though. You might have better luck with the touch up paint the dealer gave you if the chip is larger. Apply in very thin coats and take your time with it. The biggest mistake with how people use touch up paint is to just glob the brush on there. You'll want very little paint on the brush and alow it to dry between coats.
