Fluid Film® protects all known metals by creating a non-frying barrier that seals out moisture and air. With the Fluid Film® barrier in place, existing rust will be stopped on contact, and new rust and corrosion cannot develop.


Fluid Film® penetrates to the base metal, remaining active and migrating to inaccessible areas. Fluid Film® provides long term protection from the corrosive effects of salts, calcium chloride, moisture, and fertilizers.

How does Fluid Film® work?

It's never "too late" to have your vehicle protected. Fluid Film® will stop existing rust on contact. Save costly repairs on brake lines, rocker panels, springs, and rusting frames.


Fluid Film® has been providing a trusted method of corrosion protection for almost 70 years.


Let Fluid Film® protect your vehicle from rust & corrosion during the harsh winter months.

  • Eco-Friendly

  • No Solvents

  • Non-Toxic

  • Non-Hazardous

  • Long Lasting Protection

Fluid Film® has been providing corrosion protection since it was developed in 1943.

Fluid Film® embeds itself in the pores of the metal and does not wash off easily. Fluid Film® undercoating is a thick and durable formula. It is about the viscosity of a latex paint. Fluid Film® is an annual application. Bring your vehicle to a Fluid Film® applicator before the winter season, and your vehicle will be protected against corrosion or 8 -12 months in most winter environments.

It does not dry? Won't it wash off?

Because Fluid Film® remains wet, it will get an initial dusting upon application, but because it contains no solvents and will not become sticky, it will not gum up or create a built-up of dirt.

If it stays wet, won't dirt stick to the bottom of the car?

Fluid Film® products are solvent free and consist of an all natural lanolin base. Without solvents, Fluid Film® will not dry out or evaporate. When applied inside an even closed environment, such as inside vehicle doors, inside frame tubes, etc, Fluid Film® will continue to provide protection for an indefinite period of time (years).


As an example, think about the product called WD## which is over 50% mineral spirits, according to their technical data. What happens with mineral spirits, alcohol, and similar chemicals when you spill them? They evaporate. Their products work well. They penetrate, do their job, loosen the bolt, or get rid of the squeak, and evaporate very quickly.


Fluid Film® on the other hand, with no solvents, will penetrate the area, and will not dry out or evaporate. Fluid Film® will continue to provide an indefinite period of protection and lubrication in that same area.

What's the big deal about "solvent free"?

No. Fluid Film® is a non-drip, non-tacky, self-healing formula.

If it stays wet, will it drip on my driveway and on the garage floor?

Hard undercoating is generally 3-4 times the cost of a Fluid Film® application. The downside to hard undercoating is with time these tend to chip and crack. The protection is load as moisture and road salt enters these openings and gets trapped between the hard shell and the vehicle undercarriage. Corrosion will thrive in this environment and you cannot see it until it is too late because it is hidden under the cracked hard shell. Fluid Film® is a cleaner, less expensive and more effective alternative.

Why would I want to have my car undercoated every year with Fluid Film®, instead of a traditional hard-shell undercoating?

Yes. Fluid Film® does not wash off easily. Just avoid the high pressure wash on the undercarriage of the vehicle. A low pressure rinse is fine.

Can I still wash my car without washing off the Fluid Film®?

It's generally not necessary, but your Fluid Film® applicator location can provide you with aerosol cans for quick touch-up on the high-wash areas such as the wheel wells. The aerosol cans are also great for any application that needs lubrication or corrosion protection. Fluid Film® works great on battery terminals.

Can I touch-up the Fluid Film® myself during the winter season?

About Fluid Film®

When the US Navy needed to conquer the costs and delays of battling rust and corrosion in the ballast tanks of its thousands of combat and support vessels in World War II, an innovative chemist formulated a powerful weapon based on an unlikely ingredient: lanolin (wool wax). The savings were immediate. The costs of chipping, sealing, and painting were greatly reduced. The new film penetrated corrosion and rust quickly. Application was simple. Protective action was ling lasting and economical. The weapon was Fluid Film®, produced in a variety of easy use forms by Eureka Chemical Company. Operating since the early 1940's and incorporated in 1953, the company continues as a family-owned business managed by descendants of the founding chemist. From its first sea-going use in the 1940s, Fluid Film® has been proved in some of the most severe conditions; Industrial, agricultural, raw-terrain construction - even on the space shuttle. Modified over time to adapt to environmental and application considerations, it's non-toxic, non-hazardous, contains no solvents and is environmentally friendlier. Fluid Film® continues to serve as the most effective corrosion control for industry, agriculture, manufacturing, and vehicle undercoating.

Care should be taken around non oil-resistant rubber goods. May cause swelling. Fluid Film may soften some vehicle undercoatings. This includes undercoating type paints. Check with dealer/vehicle manufacturer as to compatibility.
