FLUID FILM Auto Undercoat Frequently Asked Questions.
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 lower cost and more effective alternative to the standard hard-underbody coatings. Protecting undercarriages from metal deterioration, FLUID FILM auto rustproofing also remains soft and pliable, making it self-healing, non-drying, and impossible to crack. FLUID FILM auto undercoating migrates to inaccessible areas, providing up to a full year of solid protection. Apply using a standard auto undercoating gun or airless paint sprayer.
Does the undercarriage need to be prepped first?
FLUID FILM is an excellent penetrant, so extensive prep work is not necessary. Any flaking or bubbled rust spots should be scraped off before application, as these are likely to fall off and leave an untreated bare metal area.
Should I wear a mask when undercoating my vehicle?
FLUID FILM is classified as non-toxic and non-hazardous.
It is not good for you to breathe dusts or small particles of anything. You should always wear a dust mask and eye protection when working with any chemicals.
Are there any areas on the undercarriage that I should avoid?
FLUID FILM will not harm paint. It can be sprayed directly on painted surfaces without any harmful effects. FLUID FILM has no adverse effects on plastics or oil-resistant synthetic rubbers. FLUID FILM is non-conductive and will not harm electrical connections.
Try not to get any FLUID FILM overspray on the glass windows as it can be a bit difficult to wipe off.
Does FLUID FILM attract dirt on the undercarriage?
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 build up of dirt.
Won't the FLUID FILM get washed off the undercarriage?
FLUID FILM is not water soluble, resisting splash off from water, slush and mud during driving. Naturally a certain amount of wash off will occur, however FLUID FILM will actually embed itself in the pores of metal, resisting wash off and keeping moisture and oxygen from getting to the base metal. Fluid Film remains active, migrating to inaccessible areas and protecting from moisture and road salts, even calcium chloride. Because it is a soft coating, it is going to have to be redone every year, or twice a year. Applied in fall, it will get you through a full winter season.
Can I use a pump type sprayer for applying Fluid Film?
No. FLUID FILM needs to be sprayed at 60-80 psi.
Can I thin down Fluid Film and use it in a pump sprayer?
This is not recommended. FLUID FILM is thixotropic, and will get thicker upon sitting. For best results, store at room temperature and shake or mix very well before using the product. This will help to thin it out.
Any undercoating, or paint sprayer is what is recommended for proper application. 60-80 psi works well for most applications.
What is the shelf life of Fluid Film?
In bulk form (gallons, pails, etc) the shelf life of Fluid Film is indefinite.
Will this make a mess in my driveway?
FLUID FILM is an easy "no drip" application. A drop cloth could be used to catch overspray during the application. If done in a garage, household cleaners such as Simple Green work well to cleanup any excess spray on the floor.
How do I remove FLUID FILM so that I can paint an area, and then reapply?
For equipment that is to be painted following a treatment of Fluid Film, a more vigorous cleaning is advised. A high-pressure, hot water or steam detergent wash (minimum 120F) is needed. Utilizing cleaning compounds specifically formulated to remove grease/wax as a pre-treatment process for painting are highly recommended.
How does Fluid Film® work?
Fluid Film protects all known metals by creating a non-drying 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.
It does not dry? Won’t it wash off?
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 an authorized Fluid Film applicator before the winter season, and your vehicle will be protected against corrosion for 8–12 months in most environments.
If it stays wet, won’t dirt stick to the bottom of the car ?
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 build-up of dirt.
What’s the big deal about “solvent free”?
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 enclosed environment, such as inside vehicle doors, inside frame tubes, etc., Fluid Film will 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. These 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.
If it stays wet, will it drip on my drive-way and on the garage floor ?
No. Fluid Film is a non-drip, non-tacky, self-healing formula.
Why would I want to have my car undercoated every year with Fluid Film, instead of a traditional hard-shell undercoating?
Hard undercoatings are 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 lost 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.
Can I still wash my car without washing off the Fluid Film?
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 touch-up the Fluid Film myself during the winter season?
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
