Saw this last night. A new polish called Reacta-Gloss. The most interesting part is when Alex was going through the details on how to use it; he said you go 500-2000-4000 before applying it. Notice he skipped the 1000 and not sure why. He also states that any ball (he lists them all) that initially had a polished finish will be using this new polish meaning no more 4K fast on some of the balls like the Dark Code as an example. But balls that were released with 4K fast will stay at that surface OOB which he lists as well.https://www.youtube.com/watch?v=ZnAKtriouYwIf the final sanding process winds up at 4000 and the 4k fast is at 4000, why can't you just put the polish over a 4k fast ball without doing any sanding? Looks like, to me, that you should get the same result.
Does the new polish make the ball hook a lot more?
