Just saw this - If you haven't already ordered. . I have worked with the Pinnacle XMT swirl removal products.. I wasn't impressed. Yes, they took out the big swirls, but the finish never could get perfect. Even the finest polish still left tiny micro-marring. It was pretty evident on my friend's black cts-v under a light.
I will tell you this, though. I personally use Wolfgang total swirl remover 3.0 and I will probably never use anything else. It rips through swirls, but it finishes out perfect without having to go back with several stages of finer polishes to remove micro marring. Wolfgang TSR 3.0 + Orange foam pad + Porter Cable (or flex, similar) is all you need for it to look as perfect as it's going to get.
