PolyRock uses industrial-strength resins to create an extremely durable finish that will hold up under the most extreme playing environments. Every PolyRock finish includes our Electronic Resistant Interior (ERI) coating that lines the hardware cut-out areas of each instrument. Our ERI coating prevents the instrument’s electronics from causing unwanted buzz or hum created by today’s hotter electronics.
Finally, each PolyRock Multi-Color finish is modified with light-reflecting metallics that reflect multi-colored lights from the surrounding room.
