This polishing pad is soft foam (black) and the foam is ventilated with a snake design. The ventilation enables the pad to be used flat onto the polished
surface rather than at an angle because the vents prevent the polish or
compound from spraying out the side of the pad.
Using an ventilated pad usually means the user uses it at an angle to
prevent the polish and compound from spraying out and making a mess and
waste. When the pad it used flat it greatly increases the working life of the pad. The pad will also run cooler than standard pads, so eliminating the risk of overheating the polished surface.
