Recommended for use with the Flex XC3401 VRG, this foamed wool pad provides both outstanding cutting power and an excellent finish. Foamed wool is more dense than traditional wool, which equals less linting and a better overall finish. We recommend using this pad with Meguiar's #105 or D300, or a mixture of the two. The cutting ability from this combo is outstanding and the finish is fine enough to jump straight to Menzerna PO85RD or Meguiar's #205 with a Crimson Hydro-Tech Finishing Pad. We do not recommend using this pad with a Porter Cable 7424XP or other free floating spindle DA polishers. 6.5 inches.
