Thread the backer pad onto your rotary polisher’s 5/8"-11 spindle. Hand-tighten firmly.
For Hook & Loop (HL) models: press the foam, wool, or microfiber pad squarely onto the velcro face until fully seated.
For Adhesive (GL/PSA) models: peel the liner from a PSA pad and press it firmly onto the adhesive face. Replace pad when adhesion weakens.
Start at a low RPM to seat the pad and check balance before applying polishing compound.
Apply even pressure during polishing — the urethane edge will flex to follow contours.
After use, brush off debris and store flat in a clean, dry area to preserve adhesion.
