Premium 6" low lint pads are a knitted prewashed lambswool matted to a foam interface for maximum comfort, performance, and overall user feel/experience. Great for a variety of tools. The foam interface makes this pad feel great on a rotary maching but has the durability and firmness to hold up on even a 21 mm DA machine. Works well on gelcoat to remove oxidation and can be used as a one step pad due to the amazing finish it provides. For DA, this pad is ideally used for heavy compounding bringing superior cutting abilites compared to a microfiber pad.
