gunny glide graphene lubricant Scent:Clover Mathematically verified radial-convex shape ofGunny Glide is a revolutionary graphene h BN based lubricant designed to work on all surfaces. Graphene and hexagonal boron nitride are two dimensional one atom thick materials. Graphene, a single layer of carbon atoms, is 200x stronger than steel and has more lubricity than any single material known. Graphene when suspended in a lubricant and applied to a surface will burnish itself to that surface. It not only fills any pores or defects in a surface
