The RUPES Nano iBrid Medium Foam Polishing Pad is designed to be used with the RUPES HR81ML BigFoot Nano iBrid and is currently available in two different sizes. Both sizes are made out of the same semi-coarse open cell foam as the RUPES BigFoot Medium Foam Polishing Pad and feature a durable hook and loop backing and a splayed side profile for safety. Furthermore, they both meet a specific weight target, which ensures that they work in perfect harmony with all three functional units supplied with the RUPES HR81ML BigFoot Nano iBrid. This approach, which is also used for the Nano iBrid backing plates, ensures that the machine is optimally balanced during use and that vibration levels are minimised. Over the years, the RUPES Nano iBrid 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.
