I find that 3M cubitron sandpaper does work better and last longer than other brands. But I find that the Velcro on the back loses grip with my ROS much more quickly than the grit on the paper. Does anyone else have the same problem? The pad on my ROS is pretty new and a fresh sheet grips really well.
I will say my dust collection system is not great. Is it possible that’s affecting the Velcro? #diy source
