I recently aquired a spinner, and I am enjoying the discovery of different ball reactions with different finishes.  I have decided to get my home bowling center dialed in.    

  Using an AMF Velocity,  I have experimented with ways to apply Track Magic Shine over 600, 800,  1000,  1500, and 2000 grit wet sand. I don't think Magic Shine has any grit in it.  Anyway, I have discovered that there is a huge difference between application by hand and by spinner and that the the difference is a result of the heat generated by friction.    

  I have tried application with: 1. simulated wool bonnet on a CAB.  2.  Terry cloth wrapped over CAB.  3.  Thin shop towels wrapped over CAB.  4.  Damp sponge hand held.  5.  Dry sponge hand held and 6.  A Leather Chamois wrapped around CAB.  I regret that have not kept detailed notes,  I was looking for the finish that would work for me on my home condition. I think I can share some of this reguardless.    

6.  The dry Chamois generated the most heat and quickly created a deep shine that was not tacky.  The ball looked like a marble and It felt like it would slide forever and I think this level of shine would be best for very dry lanes, or on a spare ball.   The chamois did not fullly burnish during this first trial, and I did not try to use it damp.  I did not roll the ball with this finish.

5.  The dry sponge created a deep but also very tacky shine.  Too much pressure/heat destroyed the sponge and  the tacky finish  became slick - but not to the level of the chamois.  I refinished to the very tacky state over 800 wet sand and found an easy swing from 14 at the foul line to 11 at the break point.  This shot was great for 1 1/2 games then I had to incrementally move left.

4.  The damp sponge created a nice shine that was medium tacky over green scotch brite that is approx. 600 grit wet sand.  It worked very well straight down board 7 - over 5 to 7 units of lane conditioner buffed out to 42 feet - for all 3 games of league play last night...I didn't have to move at all.   Mission accomplished with this particular ball.
