SurfPrep's focus is to learn every single day. This means we are out in the field with f)rofessionals who focus on sanding all year long. We learn what woodworkers need and we invent new products that bring value to a co m pa ny. We h ave i n n ovated a new hand sanding abrasive that is made in the U.S.A. that wil outperform and outlast anything else on the market. With this, we created the R.A.D. Pad (RevolutionaryAbrasive Design). The R.A.D. Pad is unlike the industry standard 9"Xll" abrasive sheets. The foam backing uses the same technology as our Visionary Award Winning Foam Backed Abrasives, but gives the user an option for hard to reach areas. Each sheet is - Size: 5.5" x 4.5" x 3/16" Thick 2 each of Medium, Fine, Very Fine, Super Fine 8 sheets total
