The black Force pad is the finishing pad of the 5.5in set. The picture shows a pair, both charcoal black, one face on and one from the back with its black hook-and-loop, and each has a hole through the centre. Before it in the set comes white polishing, after it red.
Lake Country gives the black pad no mechanical cutting ability. Its very soft foam is for finishing polishes, waxes, sealants and glazes, and the density of the foam keeps the pad steady on the panel while you work.
Force pads are Lake Country's dense hybrid foam pads. They are 1.25 inches thick with a tapered edge, and the maker designed them with forced rotation polishers in mind, where it found thicker pads easier to use. The backing is 5 inch, so the pad suits a 5 inch backing plate, and Lake Country says a 4 inch plate works too.
After use, wash the pad with a pad cleaner, lay it flat to dry with the backing facing up, and store it dry in a sealed bag or box.
