Wiseco ArmorGlide skirt coating is a dry film lubricant applied to the piston skirt. This coating helps reduce friction, improving performance, and will also help quiet the piston in the cylinder bore. This coating is permanently applied, and is not a break in coating, it is on the piston for the life of the part.
