I have used it with mixed results. On one vehicle, things went quite well and I was very happy with the results. Red car and the repair was not at all visible. On a dark blue metallic, my luck was no where near as good. It seems that it is somewhat of an art in getting the right drying time, right amount of product and right amount of polishing. Since it worked so well the one time, I have to feel that the problem is most likely me. Next time I will vary my routine a little and see how things go.
