I'd say it works.
Here what I did:
I resurfaced my friend's Adrenaline (and his Messenger Ti), Because he has never touched them since he bought them brand new. I suspect he has upwards of 1000 games on each of them. I did the same procedure on both of them, with the final surface finishing process being specific to each ball.
For the Ebonite Adrenaline purposes, this is what I did:
- sanded it with 220 grit to get rid of most scrtaches (I will not remove all, as that removes too much coverstock and is not essential to ball reaction.)
- treated the dull surface with Track's Clean and Dull, according to dirrections.
- Leaving the ball at 220 grit, I used Columbia's CPR: a polymer, placing the ball in the supplied plastic bag, I coated it lightly with the polymer, just to cover the surface, about 1/2 of the bottle. I left in the bag for about 24 hours. (Instructions say 2 hours)
- Cleaned the ball thoroughly with Neo-Tac's Nitro.
- brought the sanded level up to 800 grit, in stages.
- Polished it with Storm's Xtra-Shine, the equivalent to Ebonite's Factory Finish polish which I didn't have in stock. (I asked Ebo about their Factory Finish polish and I decided these were equivalent.)
- Took the surface to 1200 grit using Ebonite's Matte Finish (great stuff), following the directions.
My friend, Rob, used it the next Tuesday in our league and I would say his carry power is back, BIG TIME! The ball hits like it was new. Pins were moving for him like they haven't, all year long, up to now. The ball grabs the lane slightly earlier, as it should. (FYI I got a large coke for doing each of his balls.
No, I didn't tell him what it cost in terms of time or money.)
FYI, for whatever it's worth, the results were similar for the Messenger.
Since I never let my (bowling) balls get to the point where his were; so treating and testing CPR using any of mine will not show good or bad results.
