Kano Laboratory Aero Kroil penetrating lubricant loosens frozen metal parts - including rusted nuts and bolts - by producing a molecular affinity to metal, which gives Kroil the ability to propel itself into millionth inch spaces. Since not all frozen parts are caused by corrosion, additional research has provided for the inclusion of other molecular properties assuring that the final molecular architecture of this lubricant would also be capable of loosening frozen metal parts when other factors such as compression are more responsible for the problem.These properties enable Kroil to breaks the bonds of rust or loosens over-torqued parts to free frozen metal parts.
