Featuring water-based polyurethane resin, fade-resistant pigments, and reflective glass spheres, CRC Reflective Spray Paints and Reflective Mining Paints are used to mark hazards or objects which need to be located in low-light or dark areas, such as fire hydrants, safety equipment, guard rails, electrical switch boxes, gas meters, and boat piers. Supplied in 16 oz and 20 oz aerosol cans, respectively, spray paints and mining paints must be applied over aluminum base coat for effectiveness.
