Rustproofing and undercoating your vehicle can protect it from corrosion and rust. 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. Before rustproofing or undercoating your undercarriage, you need to consider a few things.
The advantages and disadvantages of rustproofing/undercoating your vehicle:
The best time to rustproof or apply undercoating protection is when you buy a brand-new vehicle that hasn't been driven yet. Do what many folks in Northern Virginia have done, set an appointment at APS in Fairfax to have the service performed shortly after your purchase.
This represents the best time to have an undercoating applied, as the underbody of the vehicle is probably the cleanest it will ever be.
For used vehicles, rustproofing requires the expertise of professionals who must remove existing rust before the application of the rustproofing and undercoating.
This applies most commonly to used vehicles. 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.
Electronic method. Using a weak electric current, this small device can stop the corroding effects of rust.
You can have these electronic devices installed at the dealership, or save some money and buy them from a source outside of the dealership.
The reviews on these devices are mixed.
Undercoating. This method involves spraying a tar-based substance on the exposed parts of a vehicle's underbody.
The tar-like undercoating acts as a barrier once it hardens, keeping out moisture, salt, and other substances.
This undercoating works best when applied to the undercarriage of a new vehicle. It also requires an expert application, or it can crack, letting in moisture.
Dripless oil spray. 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 useful. The spray also has a high viscosity, meaning that it does not always get into all of the nooks and crannies of your vehicle.
Drip oil spray. This is the most commonly recommended rust protection.
Drip oil sprays tend to continue to drip once applied until they dry. This dripping can last anywhere up to 48 hours after application.
Unlike the dripless varieties, the more watery nature of drip oil sprays means it gets into more areas on your vehicle, though you still need to have holes drilled in your vehicle's fenders, doors, and other areas to make sure that it gets to all the areas it needs to.
Tip: Use a tar-like undercoating for best results. A rubberized undercoating is more durable and seals better, protecting the metal from exposure to water.
While rustproofing is best applied when you first purchase a new vehicle, you can get undercoating protection for your used vehicle to keep it safe from further exposure to water, dirt, and other substances from the road.
