Funny story here....I returned one white pad because of the felt coming off and I was using the replacement this weekend. I washed it once - car wash soap like they say to use, hang wrung it out and set it aside to dry to eat lunch. I come back, slap it on my PC and spin at speed of 1 and slowly increase speed to 3. I then started buffing a panel and shortly afterwards, the PC started to vibrate really bad and the pad looked like it was moving strangely - it didnt seem concentric anymore. I was at speed 4.5 - 5.0 and immediately removed it from my paint. Just then, the pad flew off and landed in the street.
I hung my head.
My wife was watching from the house. She laughed.
I finished with my 4"
CCS pads from CMA which I absolutley love. I've used them twice as much as the 6.5" pads and the velcro on those is holding like a champ!
