Cons of Undercoating

Undercoating will work best on new vehicles that have not been exposed to road conditions. A used vehicle may already have residue on the bottom of the car or even have spots of rust and corrosion.

Rustproofing should be done every one to two years. Depending on your driving habits and climate, you can determine if you should go yearly or push it to two years.

How long does undercoating for cars last? If you live in a cold, snowy climate, near the ocean, or in other rust-prone areas, undercoating should be reapplied each year. Since road salt and de-icing treatments can make corrosion worse, it's best to undercoat your vehicle just before winter weather begins.

Ziebart charges about $120 for a car and $140 for a van or SUV for this method, and it is recommended that it be reapplied annually. The rust protection most commonly recommended by experts is a drip oil spray, with Krown and Rust Check being the leading providers.

Rubberized Undercoating

Overall, rubberized coating is generally the best option for protecting your vehicle's undercarriage, as it provides the simplest and best protective measures against rust and moisture.

If you intend to keep the vehicle for a period beyond the manufacturer's rust warranty, you should consider rustproofing. Do not purchase rustproofing from a dealer. APA recommends Krown Rust Control. Please note: Most car dealers do not recommend Krown.

When it comes to protecting vehicle underbodies, suspension components, and floor pans, Rustbuster Epoxy-Mastic 121 is recommended as an effective coating. This product forms a completely impervious, flexible, and hard barrier on the steel, preventing future rust.

Genuine Ziebart Rust Protection and Undercoating: this ensures that the underside and all upper body panels of your vehicle remain rust-free. It's inspected and renewed once a year.

Since rust normally begins on a car's underbody parts, one of the most effective ways to protect your car is to apply a protective coating that essentially acts as a seal for the underbody—undercoating. This is especially important in so-called Rust Belt states where wet and wintry weather can brutalize cars.

Woolwax® is a heavy-duty industrial grade lanolin vehicle undercoating that will survive the harshest weather and provide rust protection longer than any other annual undercoating.

Applying an undercoat to a vehicle usually only takes a single day, so long as sufficient time is given for the applied coating to fully dry and adhere to the vehicle.

The best time to have vehicle rust protection applied is definitely spring and summer. These are two periods of the year with a drier environment and when the roads are not maintained with tons of abrasives and are not constantly wet and covered with deicing salt.

Why do modern cars not rust?

Most modern cars are painted with a primer and sealer before final painting, reducing contact between the metal body and the oxygen in the air. Modern paints contain chemical additives (sometimes referred to as rust preventives) that create an invisible shield against moisture.

Rust can slowly eat away at your vehicle's undercarriage and cause permanent damage. In most cases, that damage is repairable, but depending on the extent of the damage, the repairs can be expensive.

First. If you plan on ditching your car at the end of a lease, don't bother rustproofing. It can be someone else's problem, which sounds mean but it's true. But if you're going to keep this car – and cars are lasting longer than ever – or sell it privately at some point, rustproofing is your friend.

Rustproofing is one of the most popular dealer options. However, dealer-installed rustproofing is unnecessary and might even void the section of the manufacturer's warranty that covers corrosion damage. Manufacturers add high-quality rustproofing at the factory, so the dealer doesn't need to add another coat.

Ziebart undercoating is an asphalt-based substance that's similar to tar once it's dry. It's 10 to 12 mils thick (think 20 sheets of paper) and acts as a barrier against rust and corrosion by sealing out your vehicle's underside to protect it from the harmful elements of the road.

WD-40 can help remove rust from metals like iron, chrome, and stainless steel without further damaging the surface of the metal or removing the paint.

"You have to get the rustproofing into the car's body," Ziebart said. "Drilling holes in just the right places and development of tools to spray the material where it is needed is what made the process work."

Underbody coating provides long term protection from corrosion to car's underbody. It also protects parts like internal body panels, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.

However, many new cars may not need undercoating, since they're built with rust-resistant materials. Since rust doesn't generally appear for five years on most cars, it might not be worth undercoating a new car that you don't plan to keep.
