If you’re considering undercoating your truck with fluid film, you need to know how much to use. With this expert advice, you’ll know exactly how much you need.

Thinking about protecting the underside of your truck with a nice undercoating of fluid film? If so, then knowing how much of the stuff you need to buy (and use) is important. 

You don’t want to waste money on a bunch of extra cans of it, but you also don’t want to run out before you’re finished undercoating your truck. 

So how much do you really need? 

How Much Fluid Film Does It Take To Undercoat Truck?

Depending on what kind of truck you have, and how thick you want to apply the fluid film, you’ll typically need up to about four cans of film to undercoat your truck. If you’re concerned that you aren’t going to apply it thick enough, just pick up a couple of extra cans and you’ll be good to go.

When it comes to protecting your truck from the elements, nothing beats fluid film undercoating. 

This stuff does an amazing job of keeping the underside of your truck free from rust and corrosion. 

But how much fluid film do you need to properly undercoat your truck? In this article, we will answer that question for you. 

We’ll also talk about how to know when there’s enough fluid film on the surface, and how to go about applying it. 

A topic like this one requires a mixture of technical research (to understand what fluid film is) and input from people that regularly use this stuff (to truly know how much you need). 

Since we tackled both of those avenues of information gathering, you can read through this article with the confidence that you’ll find exactly what you’re looking for. 

What is fluid film undercoating?

Fluid film is a thick, viscous liquid that dries to a waxy film. 

It’s made from lanolin, which is a wax that is secreted by sheep. 

When applied to the underside of a vehicle, fluid film forms a barrier between the metal and the elements. 

This barrier helps to prevent rust and corrosion by keeping moisture and salt away from the metal surface.

This is different from other types of rubber-based undercoatings, which are typically used far more commonly. 

The biggest difference is that fluid film does not dry and crack over time like rubber-based undercoatings. 

This makes it much more effective at preventing rust and corrosion in particular conditions and in certain elements.

What does fluid film undercoating do for your truck?

Fluid film undercoating does an amazing job of protecting the underside of your truck from rust and corrosion. 

It forms a barrier between the metal and the elements, which helps to keep moisture and salt away from the metal surface. 

This is especially effective in places that have harsh winter conditions, as the salt and moisture can cause a lot of damage to the underside of your truck.

By using this coating,  you can extend the life of your truck by years. 

It’s a great investment if you plan on keeping your truck for a long time. 

Trucks that come from places that see salt and snow often have a significant amount of rust, so using a coating like this can also help to increase the value if you ever go to resell your truck.

How many cans of fluid film does it take to undercoat a truck?

The amount of fluid film you’ll need to undercoat your truck will depend on the size of your truck. 

A small truck will require two to three cans, while a larger truck will need four to five cans. 

If you’re not sure how much fluid film you’ll need, it’s always better to err on the side of too much rather than too little.

The best way to determine how much fluid film you’ll need is to note the width and length of your truck. 

Once you have those measurements, multiply them together to get the square footage. 

This will put you in the general range of how much fluid film you’ll need to cover the entire surface. 

Of course, there will be extra square footage since the underside of your truck is not a flat rectangle, but this will give you an idea of where to start.

How much fluid film do you need?

It’s important to make sure that there’s a good amount of fluid film on the surface before you start undercoating. 

You don’t want to skimp on the amount of fluid film, as this will reduce its effectiveness. 

At the very least, it should be at least ¼ inch thick.

To make sure there’s enough fluid film, we recommend applying it in two (or more) thin coats rather than one thick coat. 

This will help to ensure that every nook and cranny is properly coated.

If there are openings and cracks in your coating, moisture and salt can get in and cause damage.

How do you undercoat a truck with fluid film?

The best way to undercoat your truck is to use a paint sprayer or just simply the cans that the coating comes in from the store. 

Either method will help to ensure that the fluid film is evenly applied and that there are no missed spots.

If you don’t have a paint sprayer, you can also use a roller or brush. 

However, it’s important to be aware that this method is more likely to result in an uneven coating.

To start, you’ll want to make sure that the surface is clean and free of any dirt or debris. 

Once the surface is clean, you can begin applying the fluid film. 

If you’re using a paint sprayer, you’ll want to hold the nozzle about 12 inches away from the surface as you apply the coating. 

If you’re using cans, you can just use the included aerosol sprayer and apply it in a similar fashion. 

Once you’ve applied the coating, you’ll want to let it dry for at least 24 hours. This will give the fluid film time to properly adhere to the surface and cure.

Once it’s cured, you can then wash your truck as usual. 

In between coats,  you’ll want to let the surface dry for at least an hour.

How long does it take to undercoat a truck with fluid film?

The entire process of undercoating a truck with fluid film should take about two to three hours. 

This includes the time it takes to clean the surface, apply the coating, and let it dry. 

Of course, this will vary depending on the size of your truck and how much fluid film you need to use.

Undercoating your truck is an important part of keeping it in good condition. 

By using fluid film, you can help to protect the underside of your truck from moisture and salt. 

This will help to extend the life of your truck and keep it looking good for years to come.
