There’s been constant debate regarding whether or not rustproofing your vehicle is worth it. Well, if you live in a climate with moderate to high moisture levels, or like to store your vehicle outdoors without cover, then protect your investment and rustproof your car immediately. To help you choose the best option for your vehicle, here are four common rustproofing methods.

Tar-Based Spray

Also known as undercoating, tar-based sprays were first introduced in the 1950s to reduce vehicle noise when driving. The application process for tar-based sprays involves spraying the substance over the wheel wells, floor panels and other exposed areas of the underbelly of your vehicle. The tar then hardens and becomes a protective shield against salt, moisture and other elements that cause rusting. However, this is a temporary fix, as moisture will seep in over time, causing the metal beneath to start corroding. The harden end-product of the spray is also vulnerable to cracking, which will create a path for moisture to enter. This is why tar-based sprays should be applied once a year to maximize rust protection.

Dripless Oil Spray

Dripless oil spray hardens soon after being applied, creating a moisture seal around your entire vehicle. In that sense, it’s quite similar to the tar-based spray method. Dripless oil sprays have a firm yet waxy texture that clings to your car’s frame without causing run-off. The application process involves discreetly drilling holes into the frame of your car for maximum coverage, to be done by a professional for the best results. Because of the high viscosity of the spray, this method tends to leave the tight seams and small crevices on your vehicle unprotected. For high efficiency, reapply dripless oil spray once a year.

Drip Oil Spray

A more intense version of the dripless oil spray method, drip oil spraying also requires holes to be drilled into your vehicle. It also happens to be the most common and most recommended rustproofing choice on the market, as it fully protects your car by covering even the smallest nooks and crevasses. It takes about two days to dry, so you can expect your vehicle to drip oil until then. To protect your driveway from oil stains, consider parking on the street to save yourself the hassle of cleaning. If you choose to protect your car with a drip oil spray, then be prepared to reapply it every year for maximum rust resistance.

Electronic Module

Lastly, there’s the newest car rustproofing and prevention method, an electronic rust protection system. Typically sold by dealerships or auto shops, electronic modules are small devices that are professionally installed directly into your vehicle. It emits a weak current through the metal body that prevents it from reacting with oxygen, therefore preventing corrosion as a whole. While this is a much less invasive rustproofing method than the previous options, there are mixed reviews regarding its overall effectiveness, as there’s no physical barrier protecting the car from moisture. It’s also a costly option, ranging from $500 to $1,000, much higher than the $100 to $150 you’d spend for the other methods.
