Hey Ric,
Yes I have used both but I never stood them side by side on the same ball to give you a fair response. If it worked fine one way, I never stripped it and put on the other polish and throw it immediately on the same shot, know what I mean? If you look at Track's website on Clean and Polish, it also shows the image of it mellowing out the backend, even more than Delayed Reaction. Sorry I can't be of more help to you....
