Make no mistake, the RUPES BigFoot Coarse Microfiber Polishing Pad is the biggest gun in the current line up of pads in the RUPES BigFoot Random Orbital Polishing System. It is engineered specifically for compounding hard OEM paint types with long-throw free-spinning dual action polishers, and is not suitable for use on other paint types (including OEM gelcoats and aftermarket resprays) or other types of machines (including gear-driven dual action polishers and rotary polishers). Compared to its foam- and wool-based equivalents in the RUPES line up, the RUPES BigFoot Coarse Microfiber Polishing Pad has a greater surface area and cuts much faster, and its unique moulded construction ensures that downward pressure is applied more evenly, thus resulting in better levelling of defects, including orange peel. The RUPES BigFoot Coarse Microfiber Polishing Pad is currently available in three sizes, with each size being designed for a specific subset of BigFoot machines (100 mm for the RUPES LHR 75E Mini BigFoot Polisher, 150 mm for the RUPES LHR 12E Duetto BigFoot Polisher, RUPES LHR 15ES BigFoot Polisher and RUPES LHR 15 Mark II BigFoot Polisher, and 170 mm for the RUPES LHR 21ES BigFoot Polisher and RUPES LHR 21 Mark II BigFoot Polisher). All three sizes feature a handy centering hole, a durable hook and loop backing and a strongly splayed side profile for safety. For the rapid correction of severe defects in hard paint types, it's hard to beat.
