How do you sand a curved car panel with a flat disc? You put a Meguiars MGS3FIS Unigrit 3 Inch Foam Interface Pad behind that disc to give it flexibility and a soft cushion to hug your vehicle's curves.
The Meguiars MGS3FIS Unigrit 3 Inch Foam Interface Pad provides a much-needed cushion between the sanding disc and the backing plate. The interface pad flexes against the curves of the body panels to promote an even sanding pattern over each sanded area. A uniform pattern is easier to polish out to a smooth shine.
The Meguiars MGS3FIS Unigrit 3 Inch Foam Interface Pad is covered with micro hook and loop fasteners from edge to edge. Use the interface pad with all Meguiars Unigrit 3 Inch Sanding and Finishing Discs.
