This is especially important for the undercarriage of your vehicle, which commonly comes into contact with substances such as water, chemicals such as salt, and other dirt and debris from the road. Without some sort of protection, the bottom of your vehicle can rust and corrode, leading to part failure.

The best time to rustproof or apply undercoating protection is when you buy a brand-new vehicle that hasn't been driven yet. In essence, ask the dealership to apply the protection before you even drive off the lot.

This represents the best time to have an undercoating applied, as the under body of the vehicle is probably the cleanest it will ever be. If you only plan on keeping the vehicle for a few years, you might consider sparing the expense and foregoing getting an undercoating applied.

While the underside of the vehicle has already been exposed to water, dirt, and other debris from the road at this point, applying an undercoating now can protect it from further exposure. When having your vehicle rustproofed or an undercoating applied, you have a few options to choose from.

Whether you prefer the latest technology or a more tried and true method, knowing what the different options are should allow you to choose the best one for your vehicle. Using a weak electric current, this small device can stop the corroding effects of rust.

This method involves spraying a tar-based substance on the exposed parts of a vehicle's under body. The tar-like undercoating acts as a barrier once it hardens, keeping out moisture, salt, and other substances.

It also requires expert application, or it can crack, letting in moisture. A wax-like substance applied to the entire body of the vehicle, it hardens once it has dried.

One of the downsides of dripless oil sprays is that you need to have holes drilled into the body of the car at specific points to make it effective. The spray also has a high viscosity, meaning that it does not always get into all the nooks and crannies of your vehicle.

While you could pay someone to apply an undercoating to your vehicle, you can also save money by doing it yourself. After removing any rust, it is time to prime and paint the underside of the vehicle.

The last step in the process requires you to apply an undercoating to the under body of your vehicle. Make sure to apply it to every part that you expect to be exposed to the road.

Allow this coat to dry for at least an hour, or longer if the instructions call for it. A rubberized undercoating is more durable and seals better, protecting the metal from exposure to water.

Photo: Shutterstock One of the newest and most heavily disputed methods of rustproofing is through an electronic rust protection system. Often sold by your dealer, an electronic module is a small device that must be professionally installed in your vehicle.

These systems emit a weak current through a vehicle’s metal body, theoretically preventing it from reacting with oxygen and corroding. Photo: Shutterstock Also known as an “undercoating,” tar-based sprays were initially introduced in the 1950s to make car rides quieter.

The procedure involves spraying a black, tar-like substance on the floor pans, wheel wells, and other exposed parts of the under body of your car, which then hardens and acts as a permanent shield against moisture, salt, and other elements. Unfortunately, over time moisture can seep behind the hard outer seal and corrode the metal beneath.

Furthermore, the rigid nature of a tar based spray makes it susceptible to cracks, which will pose an entrance for water to get in. Heart is one of the largest providers of this method of rust protection and charges approximately $150 per vehicle.

Compared to its tar-based counterpart, a dripless oil spray covers more surface area because it’s applied to more interior regions of the vehicle, but this added protection comes with a price. The application process often involves drilling holes into the frame of the vehicle to maximize the area covered.

Additionally, these sprays will often leave smaller crevices and tight seams on your vehicle unprotected because of their high viscosity. This procedure is the most common and most recommended method of rustproofing, as it’s able to fully rustproof your vehicle by penetrating all the small nooks and crannies.

The biggest knock on this method is that the sprayed oil will drip off your vehicle for about two days as it dries. To make matters even more complicated, it’s become a common practice for manufacturers to use galvanized steel in their vehicles frames.

With a coating of zinc, galvanized steel doesn’t react with oxygen the way iron does greatly reduce the risk of rust. Rustproofing will make more sense if your vehicle is regularly subjected to the elements, but if you plan to mainly do city driving in a warm climate changes are it isn’t necessary.

Finally, the decisions to rustproof has to make financial sense; you wouldn’t want to spend $1,000 rustproofing a $10,000 sedan. Rustproofing your car is an essential task to ensure that it’s protected during winter with all the salt and other harmful elements on the road.

Common places for cars to rust are the fenders, front valance, near headlights, sills, floor pans, tailgate, sub frame, jacking points and more. Ensuring these areas are covered with rust prevention spray will further extend their life span.

The best method of removing rust from the underneath of the car is by using a wire brush or an attachment on a drill. The brand also states that you don’t even need to remove rust prior to applying the formula, but we recommend that you do for the best results.

The POR-15 formula is the best rust prevention paint available that provides a heavy-duty coating that protects from all harmful elements. This means you are able to paint a range of different auto parts such as truck bed liners, areas of the chassis and more.

Available in 10 different color options Permanently seals the surface 1 gallon, 5 gallons, 1 pint, 1 quart, 8 ounces bottle sizes Resistant to cracks, chips or scratches Locks out water and air Can withstand temperatures up to 600 degrees It’s one of the best auto rustproofing formulas that provides a durable protective layer over exposed areas that suffer from corrosion.

Unlike other aerosol rust prevention spray alternatives, this formula is designed to provide a flat finish, which minimizes surface imperfections. Check it Out 3M is a huge brand in a range of industries and this anti rust protective coating is ideal for the under body.

The only drawback is that you will need multiple cans to complete the job and this could be fairly expensive when compared to the alternatives. Check it Out Waxy by Hammer ite is a rust prevention spray that is available in a clear or black formula.

Unlike the POR-15 alternative above, this formula will require heating up in order to “wake up” the rust inhibitor molecules and be easier to spray. Correct application of Waxy provides excellent rustproofing capabilities and when sprayed, the liquid formula is able to reach all the nooks and crannies.

For example, using a rust prevention paint will provide a more durable protective layer and its generally more heavy duty. When you have purchased your anti rust paint or spray, you are now ready to begin rustproofing your car.

You can then use a wire brush attachment to clear any dirt left over and remove any corrosion that is present. Personally, using a mixture of both a paint and spray such as POR-15 and Waxy is the best route and as you can see below, we used the silver POR-15 on the worst rust areas to begin with.

Be careful not to spray major components such as the brake caliper and pads as this may cause issues. Regularly repeating this process of auto rustproofing over the years will ensure your car does not suffer bad corrosion that will affect its resale value.

However, it can be more time-consuming to apply in large work areas and you will not be able to get into all the small gaps. With the build up of salty and dirty roads, be sure to check that the drain holes are all clear and water can run through.

This prevents the car metal getting in contact with any dirt or water that will cause the rust process. However, for those that are keeping classics and generally older cars on the road, protecting the under body is crucial.
