RAD Pad hand sanding abrasives are made in the U.S.A. and will outperform and outlast anything else on the market. RAD Pad stands for “Revolutionary Abrasive Design”. 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 where a tool is not always the best option. Great for both professional and DIY users!
