I have been going thru a bunch of old bowling balls, either giving them away or having fun with my ball spinner. I restored some old storm balls, Atomic Charge, Recharge to like new condition. I decided to resurface my favorite ball of all time a Green sparkle Revolution Vengeance. I shot 2 300 and 2 800's with that ball. It had some track marks, a chipped finger hole was repaired. I sanded it down to 120 wet to remove some of the minor nicks and blemishes and left on my bench in a ball cup intending to finish it today. Even if I never used this ball again I was going to polish it to make it look nice next to my 824 plaque. Damn thing split sitting on my bench overnight. I guess it will only be for display now! Good thing I have 2 NIB backups.
