I have a 5" backing plate for a PC 7424, 2 5.5" White flat Polishing pads and 2 5.5" Black flat Finessing pads. They have been rarely used, as I've only done 1 polish job with the white pad. I'd like to trade for a 3" or 3.5" backing plate for a PC 7424 and 4" pads. I can also throw in 2 microfiber bonnets for any traders out there.
