Rockler - Non-Slip Router Mat (Rating: 1)

As you can see in the images the pad leaves "residue marks" (for lack of a better term) on wood. I had to go back down to 120 grit and resand to remove the marks. The mat holds the wood but what good is it if it marks the wood.
Wish I could give 0 stars but can't. Back to the carpet pad.
