SurfPrep Medium Interface Pad, Vacuum Compatible, Yellow - 3" x 4" x 1/2"
SurfPrep Interface Pads are designed to be used with film discs/sheets. These pads allow the film sandpaper to conform to the surface countour. Use an interface pad when a backup pad is too rigid, but a foam abrasive is too soft. To use an Interface pad all that you need to do is attach the pad to a hook and loop backup pad and then attach a film abrasive to the interface pad.
