Use with 3M Ultrafine Machine Polish for the ultimate, wet-look finish.3M Perfect-It Plus Ultrafine Foam Polishing Pads were developed specifically for ultra fine polishing with 3M's Ultrafine Machine Polish. The pad utilizes 3M's patented convoluted foam design to provide smoother handling with less splatter. The 3 Inch Ultrafine Foam Polishing Pads are part of 3M's Perfect-It Denibbing System Kit. 3M Perfect-It Plus Ultrafine Foam Polishing Pads have a convoluted design that "breathes", meaning air can pass under the pad. The passage of air breaks the surface tension so the pad glides more easily over the paint. As you work, the pad holds the polish better than a flat pad to reduce splatter and product waste. The soft foam composition of 3M Perfect-It Plus Ultrafine Foam Polishing Pads is gentle and effective on all types of paint. The pad easily conforms to the curves of the vehicle to produce an even gloss from any angle. 3M Perfect-It Plus Ultrafine Foam Polishing Pads feature hook and loop backing to attach to any hook and loop backing plate measuring 3 inches or less in diameter. Depend on the 3M family of products to give you professional results every time. Remove compounding swirls, water spots, and other light paint imperfections with 3M's Perfect-It Plus Ultrafine Foam 3 inch Polishing Pads. 2 pads per pack.
