Use & Instructions
- Cut sheets to shape with a dedicated pair of scissors—film cannot be torn by hand.
- Peel the thin clear liner and apply to clean, dry surfaces such as laps, steel mandrels, plastic forms, or tabletops.
- To clear loaded debris, place the film in an ultrasonic cleaner for about one minute, then resume sanding.
Notes
- For best adhesion, degrease the surface before applying the PSA-backed sheet.
- Dispose of worn abrasive responsibly; recover sweeps from cleaning where applicable.
