The Hard Lock Super Paint Sealant G type has been upgraded and reintegrated into our lineup following a thorough review. Hard Lock's strength lies in its formula of ultra-fine polymerized amide resins. Now, that formula has been revised to enable better permeation of the paint and coating performance, resulting in improved durability and protection from contaminants. This versatile product can be used for vehicles of any color. It reduces the formation of water stains on white vehicles and leaves dark-colored vehicles with a glistening luster. This product is highly versatile and can be applied not only with a dual action polisher, but also by hand or using a rotary action polisher, all while achieving a clean finish with little residual powder.
