I have a Porter Cable 7424XP, backing plate, and 2 foam polishing pads for sale. I literally used these once and no longer plan to use them. Everything is in perfect condition. The 7424 includes the original box, pad changing tool, and manual.
The backing plate is a Meguiars W68DA for dual action polishers. It is designed for 7" pads. The pads include a Meguiars W8207 Softbuff 2.0 and a W9207 Softbuff 2.0 polishing pad. I don't think I even used one of the two pads. They are both clean and in like-new condition in the original ziplock packaging as is the backing plate.
The Meguiars stuff retails fo $70 and the PC 7424XP retails for ~$119. I will sell these for $130 shipped! It's a steal - as stated, this stuff has been used once.
Thanks - Jake
