T-Cut Headlight Polishing Compound is specially formulated to safely restore, maintain and protect all types of plastic, glass and acrylic headlights back to crystal clarity. Directions: 1) Wash with a quality shampoo and dry thoroughly, restoring one headlight at a time. 2) Use masking tape to protect the painted surface around the headlight.
