Black Hole is an easy on / easy off glaze for dark coloured vehicles and helps bring out the most from dark colours, hiding light swirls, scratches, and paint imperfections. Black Hole is designed for detailers, enthusiasts and show car owners who want the best, deepest, and wettest shine available. Can be applied as often as needed and can be topped with waxes or sealants, or just left alone for show vehicles. Can be applied by hand or machine.
