The product penetrates rust in a perfect way, and reduces friction. Effective due to its unique “motor life – metal conditioner” formula. It combines with metal on the molecular level, which means that the liquid enters the metal, like a hand cream enters pores of the skin. Perfectly suited to be used for unscrewing corroded bolts. It does not have any problems with baked-in srews. Provides long-term protection against repeated baking-in of the screw threads. Also useful for lubricating padlocks, various hinges, bicycle chains, etc.
