Has anyone had issues with these pads failing quickly? I used a blue cutting pad with the Rupes mini last night and the pad started to separate from the backing after no more than five minutes. I grabbed another pad and used very little pressure to see if that was the issue and in about the same time it also started to flare out due to coming off from the backing. I've had good luck with the microfiber pad but would like to cut using a foam pad as well for hard to reach areas. Any other pads that might work with this buffer that you use?
