what happened to mine is that the velcro came unglued from the foam. The 3M plate is just as soft as the
meguiar's, and I think its safer yet as its more thick, and as I stated earlier is all made of foam, 100%.
but back to the
Meguiar's, yeah the velcro came unglued causing "ripples" in the plate - which led to the machine throwing pads (not good as I actually made contact between the velcro and the car once when polishing.)
I don't know why this happened, I've known others who have had no problems with their plates, but myself and the guy at finishmaster have had problems??
interesting indeed.
