6" 實心 PSA MIRKA 藍色底切圓盤

These discs cut through old paint and primer much faster than the sandpaper I was using before, and the consistent grit leaves a really smooth finish. I was surprised how well the PSA backing held on a curved surface without any lifting.

The adhesive on these discs holds firm through heavy sanding sessions, no peeling or slipping at the edges. I've gotten through a full garage door prep job with just two discs, and the cut stayed consistent the whole time.

The PSA backing grabs the backing pad instantly and holds firm through the whole job. Cut through old paint without loading up, and the 6-inch size fits my sander perfectly. These discs are my new go-to for prepping metal work.
