Using various pads from this kit with my new P/C-7424 polisher, cars are coming out beautifully. Pads appear very durable after two weekends and 3 cars worth of work. They clean up well with water and appear 'like new' after 2-3 hours of polishing work. $80 seems a bit pricey for a kit where I'm only using about 70% of the contents, but then again, if they hold up to multiple projects, it's well worth it.
