I’m heavily considering getting a Nuball for Christmas. I’ve heard a lot of people say that some balls just don’t bleed and that they think the rejuvenator has no value, yet others swear by it. I’m just curious, opinions from the group, please, particularly if anybody has used the rejuvenator in combination with phase 2. What have you seen? Is it worth it?

Typically it is balls that are highly polished that do not bleed because the pores are basically clogged up with polish.  Balls that come sanded and used that way typically bleed the most because the pores are open.  This is why they say if you go to use a rejuvenator; to take to cover down to 1000 or even 500 to really open the pores up to allow for maximum bleed.  I have a Deep Freeze that came 4000 plus Factory Finish and probably have at least a few hundred games on it.  As much as I have inserted it into hot water; I get very little to bleed out.  However, I have a Scorpion that has stayed at 2000 since I bought it and have well over 125 games on it and have inserted it into hot water a couple times and within minutes, there is a layer of oil at the top of the water.  It isnt a lot but noticeable. 

If your P2 has a lot of games on it, I would sand it down to 1000 and insert it into a bucket of hot water first before investing into a machine.  This will serve as a test to see if you do in fact see some oil extracting from the ball and determine if a purchase is worth it.

I run mine thru the dishwasher and have good results.
Just don't let the wife catch me.

I just soak the ball in hot tapwater, 10 minutes, clean, 10 minutes, clean and so on until no oil is coming out any longer.  Usually takes 3 or 4 cycles.
