Kroils high solvency penetrating oils first penetrate to one-millionth inch spaces to break the bond of rust and to provide lubrication at the first molecular level. this frees the frozen metal part. the dimethyl silicones then provide extra long-lasting lubrication and rust protection. SiliKroil is not only good to loosen frozen metal parts but to supply extra lubrication in infinitely small spaces.the addition of Silicone to Kroil also enhances its water displacement qualities and improves its performance as a cutting oil.
