Dang, too soon, I was hoping someone would take by bet on this first, I could use the extra $ for tournament entries.
I admire your confidence. I will send my PayPal info, regardless.
I put an old set of pockets in the Gold Crown (practice table) that I currently have set up at my house. I quickly wiped the pockets down, but didn't put a lot of effort into scrubbing them. After about 20 minutes, the balls looked about exactly like the ones shown.
In my case, I can most definitely assure you that it has absolutely nothing to do with any sort of polishing compound. I would bet the the same for the OP.
