Time To Become Proactive With Rust: Get The Best Undercoating For Trucks.

The underside of your truck is exposed to a number of elements that accelerate the corrosion of its metal components on a daily basis. Salts, calcium, dirt and sodium chloride are just few of the inevitable substances that embed themselves on your vehicle and slowly eat away at its structure. To extend the life expectancy of you truck, this issue shouldn’t be ignored, and the only way to tackle it is by using the best undercoating for trucks you can afford.

The 3M 03584 Professional Grade Rubberized Undercoating is a cheap and simple to use 16 oz aerosol can. Its use is not limited to trucks as it can be applied to cars and recreational vehicles and requires no extra equipment or technical prerequisites in order to use.

The black protective coating that it produces is thick and consistent and can resist an array of eroding factors ranging from chipping and abrasion to rusting and weathering. Once sprayed, a uniform layer will build up and the underside of your truck will be sealed from the effects of the dirt and moisture that tends to build up under vehicles. The coating is firm enough that no dripping occurs after it is applied.

Besides its main use as protective coating for your truck, it provides fairly potent soundproofing by isolating the cabin from the noise that emanates from the engine and the outside. But keep in mind that this option would be more noticeable and effective when applied to cars rather than trucks.

To safely apply the coating, make sure to wear gloves and a protective mask. While rubberized undercoating isn’t classified as toxic or hazardous, it is very tough to remove once it gets on your skin and you’re better served not inhaling any type of chemicals.

The Rust-Oleum Automotive 254864 comes in a 32 ounce can and is applied using a small paint brush. While the process is not as simple as using a spray can, it is still relatively easy and merely requires hand steadiness and mild finesse. If working with the brush is too tedious for you, you have the option of purchasing a spray gun since the Rust-Oleum is compatible with most of the ones available in the market. It can be used on most types of vehicles including trucks and cars of all sizes.

The rubberized coating has a smell that resembles a mix of tar and enamel. It has a thick structure and spreads easily over the undercarriage. It dries up remarkably fast and you can paint over it.  Applying two layers of coating will result in a very hard sheet of rubber that doesn’t easily wear off and is enough to shield the underside for you truck for the corroding effects of salt, water, and rust.

The sound deadening ability of the coating is discernible and provides great sound insulation from outside noise and engine whir and makes for an enjoyable ride.

The TCP Global Brand Pneumatic Air Undercoating gun is a robust aluminum spray that has can be used to apply coating to the underside of your truck as well as chip guards, bed liners, and various other appliances that require coating.

The gun is light despite its solid die-cast aluminum alloy build and is easy to maneuver. It is sturdy and can handle moderate impact with little damage to the body. While it can handle pressure up to 120 PSI, the recommended pressure for an undercoating job is 56-100 PSI.

The method of usage is simple and requires no extra adjustment. You simply pour the fluid in the cup before placing the head on top. While the manufacturer advertises this item as very precise, we noticed that the spray pattern can be a little bit wider than expected. It is advisable to cover your vehicle’s exhaust system to prevent contact from the coating.

Maintaining the gun doesn’t require any work and revolves mostly around cleaning if after usage and not letting fluid residue build up. Make sure to buy the appropriate solvent for cleaning undercoating fluid and run it through the device at least two times.

This product, as its price suggests, is far from being top quality, but you’re still getting more than what you paid for.  While the rubberized coating doesn’t form as thick of a layer as you’d get from some of the better products in this list, it still spreads well and does an adequate job of sealing moisture and rust from the undercarriage of your truck. Two to three layers of coast must be applied in order to get the best result.

The main drawback of this product is the fact that the coating takes too long to dry up. It can be quite unpractical if you’re driving your truck in rough and dusty terrains as it could easily wear off.

One thing to watch out for after applying Fluid Film is repeated exposure to water. While the undercoating can handle low pressure contact with water, high-pressure wash on the underside of the truck can effectively wash off the layer.

What Aspects Should You Consider When You’re Looking For The Best Undercoating For Trucks?

 

Before deciding to rustproof your truck, you need to have a baseline understanding of what constitutes a great undercoating product.  Always look for the following characteristics:

Viscosity

A primordial aspect that should always be taken into consideration is the thickness of the coating. If it is too thin, then you will have to the face the inconvenience of having to apply extra layers, and it probably won’t be effective in protecting your vehicle from rust. Conversely, you run the risk of causing severe damage to the underside of your truck if the coating is too thick. As a result, you should always opt for products with medium thickness.

Consistency

Since the underside of your truck is often exposed to dirt and other eroding elements, the coating layer has to be firm enough to withstand it. It also has to be water proof to some extent to avoid the inconvenience of having to constantly prevent the coat from eroding when you’re washing your truck.

Simplicity

Since you’re taking a do it yourself approach to undercoating your truck, you need to have a full grasp of the process and the different variables it is impacted by, mainly the manner of how it is used and the drying time.  Look for the product with the most straightforward and intuitive method of application such as those that are applied with an aerosol, and avoid any coating process that requires some professional know-how.

Price

It should be reasonably priced enough to deter you from resorting to hard-shell undercoating.

If you choose the right product then the process is fairly simple and you should be able to do it yourself. The Amazon customer review section is a good a place to find detailed descriptions of how the coat is applied, and the top review often has pictures that walk you through it step by step. If you still don’t trust your ability to do it you can always take your truck to a repair shop.
