Using Advanced Duraflex Technology, SAND-LOOP FLEX offers a semi-permanent superior sanding experience. The ultra strong adhesive in the backing holds the abrasive grains strong and tight so they won’t come off easily offering a longer lifespan than any other typical sanding sponges available.

Dura-Flex Technology

Duraflex Technology

High density sponge is laminated with urethane film providing a soft grip and firm sanding surface. Ultra high-heat adhesion holds the abrasive grains deeply rooted inside the backing so abrasive grains stay in place longer increasing its lifespan for semi-permanent use. Plastic residues come off easily due to the roomy space between the abrasive grains.

    I use the #800 with every kit that requires sanding round curved pieces. A prime product from Gun Primer and an essential for your toolbox.
