SOLVED! Krown vs Fluid Film

Krown vs Fluid Film

The corrosion’s undeniably devastating force is the heaviest threat to the ones who have a vehicle.

If your vehicle is consistently exposed to numerous elements such as wind, rain, snow, and sun which can be the cause of a quick deterioration of the metal.

Loss of value and poor appearance can be the result of the metal being deteriorated, but not just those, also hazardous safety issues too.

Road salt, brine, and debris can also be the reason why metal and electrical connections under-vehicle is eaten whenever they kick up and cling.

This article will give clarity on what is the difference between Krown and Fluid Film.

Fluid Film:

An intricate heating and blending process is used in manufacturing Fluid Film with the combination of unrefined wool wax along with selective polar agents and corrosion inhibitors.

It creates a unique lanolin-based formulation that puts a stop to existing rust on contact.

In terms of penetrating contact, it generates a fluid, self-healing barrier that is always present and active which don’t chip or crack, protecting the undercoating of vehicle and metals that are exposed for extended periods.

Fluid Flim is safe to use with any metal, it will stop pitting in chrome.

It can avoid harm to most paints or plastic, and has atypical lubricating properties which penetrate to end squeaks and gives almost an endless lubricity for all parts that are moving.

Fluid Film is electrically non-conductive and has a high flash point and a narrow, flexible configuration which makes it a perfect protectant for battery terminals and electrical connections.

A friendly reminder, care should be taken around non-oil-resistant rubber goods because they can cause swelling. FLUID FILM can soften some vehicle undercoating.


It is capable of penetrating the base metal, which provides a protective barrier from the corrosive effects of salts, sodium chloride and calcium, fertilizers, and pesticides that last.

Fluid Film can offer an easy “no-drip” application and a cheaper and more effective alternative to the original hard-underbody coatings.

It can protect the original coating from metal deterioration and remains soft and pliable. Fluid Flim can protect the undercoating, making it non-drying, self-healing, and impossible to crack.

It also spread to unreachable areas, providing 12 months of proper protection. One gallon of solution should be enough to cover one vehicle.

It can also soften the undercoating of some vehicles. It also protects and shines all chrome, for example, wheels and rims. It can also keep the bug from attaching to chrome bumpers.

Fluid Film can also stop pitting in chrome and has the capability of protecting wheels from brake dust deterioration.


Krown is based on petroleum to inhibit rust which is designed to inhibit or slow down corrosion on the vehicle that you are using.

One of the ideal advantages of Krown is that it does not have solvents, making it ideal for the health of the environment.

The Krown solution is non-flammable, non-reactive, and non-corrosive, for it to be applied in any weather you can name, and ensures you to work as a lubricant on many parts that are moving.

However, its downside is you may experience or encounter dripping off the excess product.

The solution is it needs to be thin enough for it to properly reach and spread into the tight seams of the vehicle you are using. Within the first 24-48 hours of application, this can cause minimal dripping.

If your vehicle has not experienced being protected yet, then now is the best time when to spray it.

From the corrosions perspective, the process of corrosion is most active in the months of summer and spring due to the increase in temperature.

However, talking about the yearly application of Krown, regardless of the time of year it is being applied, will provide one year of protection against corrosion.


To work effectively, the Krown must get into the seams and around spot welds.

For the rust inhibitor to be effective, it needs to be thin enough to penetrate anywhere that any liquid can, as the moisture is the one that causes corrosion.

After the areas were being penetrated by the solution, the excess product will drip off.

Most of the time the dripping occurs within one to two days with a very small amount, if any, dripping after that point. Just like the Fluid Film Krown is also environmentally friendly.


Both are very good. It is up to the customer which one he or she preferred the most.

The important thing is you already know what the difference between the Fluid Film and Krown is.

In the end, it is the budget and other factors that might affect you to buy that will make the final decision.
