HinderRUST S4.0 is our standard version. It is longer-lasting and more difficult to remove. S4.0 is good for most rust-control and lubricating needs, including tools, recreational equipment, wiring, forklifts, agricultural devices, garden art, battery terminals, industrial use, plus marine applications such as wire ropes and cables. Think S4.0 for Standard.
Surface protection for metal parts that need protection before and after exposure to the elements. Engineered to stop rust before it starts, and to stop rust that has started. Strong surface adhesion. Very hard to remove by exposure to normal weather elements. No rust inhibitor is considered permanent — to ensure long-lasting protection, reapply as needed.
Standard surface protection. Extreme surface adhesion and aggressive wetting across the surface and between mating parts. Hard to remove.
