Advantages ranging from greater convenience to better performance 3M™ Perfect-It™ Back-up Pad addresses the need for auto body shops to achieve professional-level results while boosting overall shop productivity. Our back-up pad delivers on multiple counts including providing a quick-change advantage and producing exceptional finishes on today's automotive paints. Our pad provides a secure, no-slip attachment, yet allows for easy removal of abrasive discs when necessary. We recommend this pad for producing professional quality finishes on gelcoat and paints.Part of the 3M™ Perfect-It™ SystemThese back-up pads are all part of our 3M™ Perfect-It™ system, which delivers better overall finishes with deeper color and gloss. When used with compounding pads, it will help remove defects with greater thoroughness and less time. The backup pad provides cushioning support to help smooth and refine an automotive finish. That same support will help polish surfaces to a high gloss. Enjoy the Ease and Speed of the Hookit Attachment SystemOur back-up pad uses the 3M™ Hookit™ attachment system for easy replacement of abrasive discs. Simply press on the abrasive disc to get a secure grip, and then peel it away for easy removal. Hookit™ is the perfect time-saving answer when you're switching between abrasive grits frequently. Best of all, you can remove and reattach an abrasive that still has a useful service life. Let's say you need to switch to a different grit but the abrasives on the disc you're currently using are not fully spent. Simply remove it and reattach later. Hookit™ ensures that you will get the same secure hold, which is an important advantage compared to pressure sensitive discs where the adhesive may be compromised by dust and air after the disc has been removed.
