The Softer Side of Paint Prep
We designed our 3M Hookit Painter’s Abrasive Disc Back-up Pad for auto body sanding jobs requiring finer abrasive grades such as prep sanding for color, primer and clear coat, where added support and control are important. The 6? diameter soft-density foam body has a 15? taper for flexibility when sanding along contours or close to edges. The disc pad features 5/16-24 external threads which are compatible with orbital or random orbital sanders that have 5/16-24 internal threads.
Our Hookit Attachment System
The Hookit hook-and-loop feature makes disc attachment, removal, and re-attachment clean and easy, and facilitates use and re-use of the disc for the extent of the abrasive life. Hookit disc pads have J-shaped hooks of the type most commonly used in everyday hook-and-loop applications. Hookit disc pads grip the brushed nylon loop backings of 3M Hookit discs and provide a finer finish than do adhesive backed discs. The Hookit system is designed for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris.
