I used this product on my 2008 Mazdaspeed3 (the car I bought because BMW refuses to bring the delightful 1 series hatch here). The car is black and naturally below the black paint is a lighter colored primer (why do they DO this?) Because the car has over 30k miles driven in Houston it has stone chips a-plenty! It's a damn shame to look at a 2 year old car and cringe because of the way it looks (and I try to avoid situations that are guaranteed to get you peppered with road debris). None the less our test vehicle is peppered indeed and so out of desperation, I ordered a Dr.Colorchip kit in Mazda's color for a metal-flake black. The folks at Dr.Colorchip say they make your paint up when you order it and I believe it -everything in the kit was fresh and it arrived in a timely manner. Being as I'm writing about a black car, this may not mean much, but the color match was spot on. The kit has everything you need to fix stone chips, but I have a few suggestions to help the "fence sitters" along (I was one until I finally couldn't stand the way my car looked,and bit the bullet). Before colorchipping your car be sure you have plenty of paper towels handy and I recommend going to the auto parts store and getting a small bottle of acetone to help with clean up. BTW, I got my acetone at O'Reilly's and it was relatively cheap. Start off by cleaning the area to be repaired with rubbing alcohol to remove any wax that might mess with adhesion of touch up paint.Dr.Colorchip recommends using the enclosed brush to Dab, then smear, wait about 2-5 minutes and then blend in the repairs with their prefast solution. They enclose a glove to wear while doing all this dabbing but I abandoned it right away and simply used my fingers to do the smearing - much easier and you can get a "feel" for what you are doing. The acetone and paper towels help clean up your fingers and the little paint brush enclosed with the kit. The supplied paint dries VERY fast so don't plan on doing any more than 2 or 3 chips at a time - I found that after dabbing and smearing 3 chips, the paint on the brush was beginning to thicken and I was near running out of fingers any way, so I stopped at 3 chips per run. After dapping and smearing go clean the dabbing brush and your fingers up to prepare for the next round. By the time your are done with the clean up it's time to prefast the smeared paint off. I cut a tee shirt up into 4 inch by 4 inch squares and using the prefast solution on them I gently let the shirt material and prefast solution cut the paint off the surrounding area and then polished the area with the kit enclosed microfiber towel. Dr.Colorchip says the prefast solution polishes down to an amazing shine and they are not kidding. After dabbing and smearing and prefasting for about 3 hours the front of my car looks great - she's all black again and shiny to boot!!! Now. this product colors in chips but doesn't really fill them in. In my case the color match was perfect but you can look and see where the paint is not level. If someone was inclined to work with the kit a while, they may be able to completely fill a chip in, but I just don't have time for all that; I am completely satisfied with the product as the front of the car looks much, much better than it did before. I even have enough of the kit left for upcoming chips that are sure to develop as the miles pile up. One note about the acetone though, it is highly corrosive to auto paint so I was sure to have the finger and brush cleaning operation way away from the car itself - WE DON'T WANT TO HAVE AN ACCIDENT WITH THAT STUFF! I realize that all this is worthless without pictures but quite frankly, I was sort of scared silly doing this for the first time (remember the part about fence sitting) and I didn't want to be screwing around with a camera while trying to get a grip on what the hell I was doing. So there you have it - a Dr.Colorchip review and a satisfied customer. This company advertises in Roundel all the time meaning they support our car club. I am happy to report their product did very well for me and I recommend it. Sorry for the too long post. Cheers!
