Has this happened to anyone, or has anyone ever seen this before? I was using my PC7424 on my Vette this evening and the backing plate fell apart and scratched the crap out of the car. I had just finished the hood and was moving to the front quarter panel of the passenger side when I noticed some small yellowish debris. I thought it was the SHR and moved the PC upward toward the hood to turn it off when all of a sudden all hell broke loose.The pad shifted and the backing plate, or what was left of it came in contact with the car. The yellowish debris is very sticky and feels like warm marshmallows. I pulled out the 4" spot pads and it took me over an hour to get the scratch out!
