Has anyone tried 3M Finesse IT II or III. I had a chance to try this recently and for swirl marks it works real good by hand. It is a rubbing compond so you do need to go easy. I just wanted to get some feedback. I ran out of DACP and someone loaned me the 3M stuff. It is not cheap as a quart is $38.00. If anyone knows where I can get it cheaper that would be nice. Thanks!
