3M Perfect-It backup pad allows for easy attachment, quick removal and accurate centering of compounding or polishing pads. We used our 3M Hookit attachment system for these pads to enhance convenience and boost productivity with quick-change of abrasive discs. The need for auto body shops to achieve professional-level results while boosting overall shop productivity. Our backup 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. These backup 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. Our backup 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.
