3M 3 Inch x 25-7/32 Inch 800 Grit Blue Trizact Belt - 5 Pack
A6 is the finest grit in the Trizact aluminum oxide mateiral. You should be able to move to either a felt belt with cerium oxide or a cerium impregnated belt for a polish after this.
- 3M's 272LA Trizact material is an embedded aluminum oxide in a randomized pyramidal structure to quick abrasion to surfaces
- The 272LA material is on a thinner belt backing and requires extra pressure for best results. This also generates heat on your glass, so take frequent breaks to prevent thermal shock on your glass
