Your referring to Ron's video "THE DIFFERENCE BETWEEN POLISH AND SHINED WITH A SANDING PAD"
https://www.youtube.com/watch?v=-KXdnef5LeA
First off he's kind of misleading about the Storm Step Two "Finishing Compound" and how the 320 to 1500 doesn't give the ball a 1500 grit surface it really gives it a 5000 grit surface.
What he didn't bother to tell you is, That the 320-1500 is in US ANSI/Cami Grit scale (Storm said that I asked them awhile back) not the Europeon P-Scale that Abralon and The Tru-cut pads use that he's comparing it too.
1500 ANSI/CAMI (which is about 2-3 microns in size) if you convert that to P-Scale it is about 4000-5000 grit (which is also about 2-3 microns in size).
So it is giving the ball a 1500 grit surface!
Next he says it's the liquid the grit is suspended in (Carrier Medium) that affects the ball motion, That's suppose to be the "film" that's left on the ball.
So he proceeds to do a comparison of pad vs polish.
He takes the ball sanded at 3000 first then polishes it with the the 5000P grit pad.
He throws a inside shot (3rd arrow) it hits heavy in the pocket and he say's look how it makes a aggressive move.
He then throws a outside shot hits pocket and says look how more angle and aggressive it is.
next he demos the ball with polish
He takes the ball that's already polish/sanded at 5000P (You can see it's not as dull as it was at the start of the video when he said it was at 3000) and adds the Step two on top of that. That would have made it a even smoother surface, So the comparison test is basically meaningless now.
His First shot he doesn't throw a inside shot (3rd arrow) like he'd did before so there no comparsion there to be made.
As for the comparisons of his miss left shots, theres virtually no difference in them that can't just be attributed to variances in his release. So it doesn't really prove there's a film on the ball.
He say's there a "Massive difference" between pad and polish , but that video doesn't really show it.
Even if there was a film from the carrier medium left on the ball, it would have disappeared after just a few shots in practice (Radicals throwbot tests showed that the ball surface changes after only a few shots and by the end of the game it's totally changed), assuming it wasn't removed by cleaning the ball after polishing first, so it really wouldn't have been a issue.
A interesting thing is to watch Ron's video "Step 2 Compound vs. TruCut Polish What is the Difference?"
https://www.youtube.com/watch?v=_PmhPIoai0o
In it he point's out that polish (like the Tru-cut polish) and finishing compounds (like step two) are not the samething and that they like using Step two in the proshop on the spinner, The Tru-cut polish is made more for using by hand at the laneside. But He doesn't say anything about them leaving performance affecting films on the balls, So it kind of looks like whats said depends on whats trying to being sold.
