I have used the Purple Stuff Bowling Ball Cleaner for about 2 year. It's a very good product. Better then many other Ball cleaner.
TruCut Sanding Pads I used for a few years now. It last much longer, has a great impact as it does not need like Abralon that many sanding. I used max 2 up/down sanding instead 5 or more. Plus the TruCut Sanding pads with it's tiny holes, it doesnt get used up so quick. Life After Death and Life extender I had not yet any experience as it only arrived today. However, CTD has a great and fast respond and order shipping system. Very appreciate.
