I have had a few people ask me about Abralon pads and where to get them. Here is the cheapest that I have found, $2.99 ea.  Grits 180, 360, 500, 1000, 2000 and 4000. Let me know if you find them cheaper elsewhere.

 Everyone that uses a spinner has their preference when working coverstock.  Most of us will use sandpaper and scotchbrite which are the best known methods. But my favorite is Abralon pads. I get 25-30 resurfaces with each pad, quick, easy and sand lines disappear.

Another great product that I use for surface finish is made by 3M.  I guarantee if you use Quick Cut or other sand based compounds you will throw them away when you use this.

3M Perfect-It III Extra Cut Rubbing Compound (N051131-05940)

It only takes a few drops and you won't believe the finish.  This is used by body shops to get the fine scratches out of High end vehicles like Lexus and such.

Steven, I never tried it, always use it by hand.  Back is sponge rubber.

I bought pads from this site:

$24.70 plus 6.95 shipping for one of each of the six grits mentioned above (6% tax if shipped to a PA address).  Each pad is 3 2/3" x 9 1/2" so you can cut each in half and have two that are about the size of the round ones. They also sell them individually for $4.95.

I can't imagine sanding a bowling ball with 4000 grit!
