The destructive force of corrosion is the single greatest threat to your vehicle. Constant exposure to a wide range of elements such as sun, rain, wind and snow can lead to rapid deterioration of metal, not only resulting in poor appearance and loss of value, but hazardous safety issues as well. Road salt, brine and debris also kick up and cling to vehicle under-bodies, eating away at metal, electrical connections, hydraulic lines and fuel lines!

FLUID FILMŪ 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. Electrically non conductive, FLUID FILMŪ has a high flash point and a thin, flexible composition, making it a perfect protectant for battery terminals and electrical connections also.

 Creeps into all seams and cavaties.  Locking out oxygen and moisture.

 Can I paint over this or is it available in different colors?
     No.  It cannot be painted.  It is as thick as pudding and paint will NOT stick.  It does NOT come in different colors.  It can be removed with hot pressure wash and detergent.

 What color is it?
    It is a clearish slightly yellow gel that is applied with high pressure.
  Does it stink?
    It certainly has an "earthy" stale beer smell that goes away in a few days.

 Does it fix the rust?
   It doesn't FIX the rust.  It encapsulates it and prevents it from spreading by chemically bonding with the metal and blocking water and oxygen.  It does NOT change the appearance of rust.  Maybe makes it darker over time.

 It it safe?
   Fluid-Film is Non-toxic and safe.  Has no solvents.  Safe for just about all painted finishes, chromes and plastics.
 How do you treat a vehicle?
   The underside is checked for cleanliness and cleaned if needed.  Treatment is applied inside of frame rails with a complete coverage, outer frame, inside rocker panels, fenders, panels, and inside door sills using various wands, sprayers and brushes as needed.

 How long will this take?
   Plan on dropping your vehicle off for at least an hour.  Peak demand will take longer for me to treat.  And the size of vehicles too.

 This sounds too good to be true. Is this a gimmick?
   I have repaired rusty cars and metal for YEARS now and it made my life miserable.  I have tried those "Undercoatings" and paints and POR products to no avail.  I read up on this product and have been using it for a while now and I am a believer.  A "self-healing" product seems to make more sense to me than applying a hard paint or covering that will flake off and trap water.

  Do I need to re-apply this?
    Unfortunately it does wear off over time when exposed to the wear and tear of rain and whatever.  It WILL protect for a looong time but I suggest a treatment annually.   Any treatment INSIDE of panels will stay for a long time but floorpans and wheel wells should be treated yearly.   Re-treatment is less then full treatment.  See pricing.
