If I am polishing a tight radius, which size Flexible Backer Pad should I use?
If you are polishing a tight radius, Alpha® recommends using the Alpha® Ceramica or Ceramica EX polishing discs together with an undersized Flexible Backer Pad. Using an undersized backer pad will allow the polishing disc to conform to the radius allowing the polishing disc to polish the material easily and quickly.
The Flexible Backer Pads are WET use only, can I use them for my dry polishing applications?
No. The Alpha® Flexible Backer Pads are to be used for wet polishing applications only.
