PRODUCT FAQ

  1. What surfaces can I use the 3M™ Hookit™ Flexible Foam Abrasive Disc 33557 on?

    Great question! The 3M™ Hookit™ Flexible Foam Abrasive Discs are designed for a variety of surfaces, including primer, paint, clear coat, and even blending and finishing tasks. They’re fantastic for use on contoured or curved areas, thanks to their flexibility.

  2. What grit is the 3M™ Hookit™ Flexible Foam Abrasive Disc 33557, and what does it mean?

    The “P400” grit means this disc is in the fine range, making it perfect for tasks like final sanding before painting. It helps you achieve a smooth finish without deep scratches—ideal for preparing surfaces or refining other abrasives’ work.

  3. How does the Hookit™ attachment system work?

    The Hookit™ system uses a handy hook-and-loop backing—much like Velcro! This makes swapping discs quick and easy, so you spend less time switching and more time getting great results. Just press the disc onto your sander's pad, and peel it off when you're ready to change!
