I've never had great success with Optimum Polishes. I used to own the whole line but then I went to Menzerna and the results are so much better. The unlimited break-down time of the Optimum products means you'll be buffing a panel for 10 minutes without much effect. Sorry for the rant, but after stepping-up to the Menzerna line I really do have a dislike for Optimum. Even Optimum's latest version of hyper compound and a light-cut pad on the rotary didn't touch the light swirls on my friend's Evo.

Velociabstract...Thanks for reading my thread What color is the car? You are definitely heading in the right directions though. The swirls probably can't come out because you have not been able to cut the clearcoat enough to the point where the surface is flat. Don't be afraid of speed 6! Use it, and use it almost always.

Mike-in-Orange...Unfortunately, I still am not too familiar with the Meguire's line of polishes. But, I hear M105 is awesome.
