Coming in at less than half the weight of the competition with similar ice retention, the Rugged Road 45 is unlike anything else on the market. The secret is in the Rigorite coating. Rigorite is an innovative proprietary spray that was originally developed for many military applications, including blast-proofing the walls of the Pentagon. It is strong enough to support the weight on an entire Jeep, and tough enough to survive a drop off a mountainside.
