The 3M Hookit 7100141693 Open Coated Film Disc is designed for fine sanding on various surfaces including plastics, gel coats, and polyurethane substrates. The disc is six inches in diameter and features a P400 grit, which falls under the extra fine grade. Its aluminum oxide abrasive and durable film backing provide longevity and consistent performance in high-production environments.
This disc allows for efficient spot repairs and finishing tasks. Its design reduces edge tearing and extends service life compared to standard paper backings.
