It’s coming to be that time of year again. Fluid Film! Protect your vehicles from salt and rust! This is a service I provide. Most cars $250 suvs and trucks $300 and up. FLUID FILM® penetrates to the base metal, providing a lasting, protective barrier from the corrosive effects of salts, calcium and sodium chloride, pesticides and fertilizers. Offering an easy “no drip” application, FLUID FILM offers a cheaper and more effective alternative to the standard hard-underbody coatings. Protecting undercoatings from metal deterioration, FLUID FILM also remains soft and pliable, making it self-healing, non-drying, and impossible to crack. FLUID FILM migrates to inaccessible areas, providing solid protection. FLUID FILM is manufactured using an intricate heating and blending process, which combines unrefined wool wax with selective polar agents and corrosion inhibitors, creating a unique, lanolin-based formulation that stops existing rust on contact. Penetrating on contact, it creates a fluid, self-healing barrier that is always active and will not chip or crack, protecting vehicle undercoating’s and exposed metals for extended periods of time. Safe for use on all metals, it will stop pitting in chrome, will not harm most paints or plastic, and has exceptional lubricating properties, penetrating to stop squeaks and provide lasting lubricity for all moving parts. Start making your appointments now we will be starting it September 1 and going on until the first salt hits the ground. This is done at my shop in Mchenry.
