This is the only auto rim detailing brush kit that will get in to those tough spots on your third gen Trans Am, GTA, TTA or Grand National with the honeycomb rims, circa 1985-1992. Made of Nylon with pipe center, these are rigid but can be shaped. The kit includes all brushes shown on the picture, many of which fit the small holes in the "honeycomb" part of the rim perfectly. Note: To be used in conjunction with rim cleaner appropriate for your finish. Please use safety goggles and be sure to use carefully.
