We have become big fans of the RUPES BigFoot Random Orbital Polishing System, and the colour coded pads really do complement the various compounds and free-spinning dual action polishers perfectly. The RUPES BigFoot Medium Foam 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 180 mm for the RUPES LHR 21ES BigFoot Polisher and RUPES LHR 21 Mark II BigFoot Polisher). All three sizes are made out of the same semi-coarse open cell foam and feature a centering hole, a durable hook and loop backing and a strongly splayed side profile for safety. Furthermore, they all meet a specific weight target, which ensures that they work in perfect harmony with the counterbalance in the machines they are intended to be used with. This approach, which is also used for the BigFoot backing plates, ensures that each machine is optimally balanced during use and that vibration levels are minimised. Over the years, the RUPES BigFoot Medium Foam Polishing Pad has gained a reputation for being very fragile, with some users complaining that its durability is poor. In our experience, you do have to be careful when using it, because its stiff yet brittle nature does make it susceptible to being torn if it is run into, or over, sharp edges, but as long as good technique is employed then it performs very well.
