Mirka Mirlon pads are three dimensional abrasives aimed mainly at the automotive industries, but an excellent product for woodworkers too. They have many advantages over conventional abrasives in that the open web design is non-clogging. You can use them wet or dry and they're ideally suited to flat or contoured surfaces. Available in three different grades this package gives you ten of each: 320g for general purpose use, 360g for denibbing finishes and 1,500g for blending, smoothing and polishing with waxes.-bg
