I've also purchased chip repair kits from ChipEx. Use this for light "road rash" that sometimes shows up after a long road trip. Their product(s) are much better than DrColorChip - MHO. (Note: DrColorChip was one of those vendors that told me Graphite Gray & Machine Gray were the same color; only a name change. I asked him to put that in writing if I bought product from him & told him he would pay to have my entire car re-painted when the color didn't match. He told me to take my business elsewhere.)
