Gold Class seems to do its best on slightly less than perfect finishes. I've always been a fan of #7 till you drop, then #26, but dark colors seem to do better with Gold Class. IMO the 2-step is still the best for ultimate results. With Gold Class just save some #34 to get all the white dust that comes with using it. I can't promise you how much more Zymol will shine, but I can promise you that you will labor much harder with the Zymol.

Let us know how it turns out...Lee
