Hook & Loop Sanding Pads â Frequently Asked Questions
â Can I use these discs with my random orbital sander?
Yes, as long as your sander has a 50mm or 75mm hookâandâloop backing pad. They fit most palm sanders, orbital sanders, and drillâattachment backing plates. Doubleâcheck your toolâs pad diameter before ordering.
â Are they safe for automotive paint and clear coat?
Absolutely. The foam cushioning prevents digging and helps you sand evenly. For paint correction, use finer grits (1500â3000) wet to achieve a factoryâsmooth, swirlâfree finish without burning through the clear coat.
â Do they clog quickly when sanding wood or drywall?
The openâcoat design resists loading. With wood or drywall, tap the disc occasionally to clear dust. When used wet on metal or painted surfaces, clogging is virtually eliminated.
â What grit should I start with for rust or scratch removal?
For heavy rust or deep scratches, begin with 80 or 120 grit. For surface rust or light oxidation, 240-grit works well. Then progress through finer grits (e.g., 400 â 800 â 1500) to smooth the surface before priming or painting.
â Can I hand sand with these foam discs?
Definitely. The foam backing makes them comfortable to hold and they follow contours easily. Both wet and dry sanding methods work equally well for manual use on body filler, plastic, or small touchâup jobs.
