I've used my PC many time to polish scratches out of plastic toys. I've wet sanded and PC polished plastic covers from turntables. Tried to polish a stainless steel sink that didn't do so well. Buffed a spot on the vinyl floor one night to see what would happen. That didn't go over real well with my wife since it was slippery so I quickly got some degreaser and stripped off the wax. I shined up an entrance way many years ago with Pledge. She wiped out when she walked in from work. Buffed bathroom ceramic wall tile one time with the PC too.
