My best answer that I can come up with is that you will see a little bit more length out of the ball on carrydown situations. Typically, after putting Elixer on a ball, it tends to act like you smoothed up the surface one notch or so versus how it would skid before. So, if you have a ball that is scuffed to about 600 grit, the ball will react like it is scuffed at 800 grit or so. I believe that the answer to your question would be that the ball will still work, but in order to keep the reaction at the same level as it was before the Elixer, you need to scuff the ball down 1 notch before applying Elixer to the ball. You will notice more of a reaction change on a dull ball than you will on a polished ball. So, if you have a ball scuffed at 600 and you want to keep it that way, you might want to take the ball down to 320 to 400 before applying the Elixer to it. If the ball is at 1000 and you want to keep it there, take the surface down to about 800 before applying Elixer.
For my dull particle stuff, I scuff it with green ScotchBrite before adding Elixer.
