Mirka Polarstar Sanding Disc.

Especially developed to efficiently tackle the latest demanding coating applications, Polarstar quickly produces a fine, consistent surface finish and combines that with superb durability due to an excellent resistance to clogging. The polyester film backing material creates a more flexible and much smoother abrasive surface, compared to paper backing. In particular, it offers outstanding performance on hard tooling gel coats and scratch-resistant clear coats.
