A three-bottle set of NOVUS #1, #2, and #3 plastic polishes plus a large cleaning cloth, intended for maintaining acrylic dome and flat ports on underwater housings. NOVUS #1 gently cleans most plastics without scratching and leaves a fog-resistant shine, NOVUS #2 removes fine scratches and haziness, and NOVUS #3 addresses heavier scratches on acrylic. Ikelite notes that scratch removal is not guaranteed and that deep damage may require professional repair rather than polishing.
