Deep Creep's fast acting, petroleum based formula quickly penetrates rusted parts, lubricates moving metal parts, disperses moisture, and cuts through grease, engine varnish and road tar. It withstands heat better than other penetrating oils, allowing you to use it in combination with a torch to loosen a badly rusted part. Deep Creep has hundreds of household and workshop uses. Deep Creep's unique spray can even works with the can held upside down so you can use it in difficult-to-reach applications.
