Making the Difference Between Good Sanding and Great Sanding
Your sandpaper is just the start – to get the best finish, it takes the right tools. Our 3M™ Sanding Blocks are designed to help you attain your best, fastest auto body repairs involving body filler, putty and primer. These sanding blocks are shaped to fit into your hand for comfort, so you can sand longer and more intuitively. The rubber construction of the block delivers a combination of durability and conformability. It helps ensure that the sandpaper stays flat against the automotive body surface, even around curves and contours. Internal attachment pins hold the sandpaper firmly to the block, which prevents it from sliding and helps prolong the life of the sheet. This simple tool makes an amazing difference in consistency and overall results in auto body sanding.
Recommended Applications
- Hand sanding of primers, putty or body filler
- Suitable for wet or dry sanding
- For use on metal, drywall, wood, plastic, fiberglass and others
