    (#200/ #400/ #600/ #800)


  • Application of Duraflex Technology for semi-permanent use

  • 5 to 10 times more durable compared to other typical products

  • Ultra density sponge offers superior sanding experience

  • Thick and compact size provides comfortable grip

  • 100% wet-sanding friendly and can be cleaned with water for reuse

Duraflex Technology

GUNPRIMER’s distinctive semi-permanent technology

The new standard of sanding tools


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 therefore abrasive grains stay in place longer which increases its lifespan for semi-permanent use. Plastic residues come off easily due to roomy space between the abrasive grains.
