Ziebart Rust Protection with Undercoating vs Oiling: What You Need to Know

December 09, 2021

No matter how advanced vehicles have become over time, one thing remains true – they still rust and corrode. Maybe you’ve considered rust protection and undercoating to help your car or truck last as long as possible, but with the different options out there, how do you know which type is right for you? We’ll get into the differences between Ziebart rust protection with undercoating vs. oiling, but first, let’s start with the basics: 

What are Rust and Corrosion and Why are They Dangerous? 

Rust forms when iron is exposed to water and air, and although iron and iron alloys are very strong metals, rust makes them extremely brittle. Corrosion occurs when most or all of the atoms on a metal surface are oxidized, damaging the entire surface. Flaking and crumbling rust and corrosion can jeopardize the safety of yourself and your passengers while on the road. This is especially true during colder months, since ice-melting agents like road salt only help to speed up these chemical reactions from happening on your car’s undercarriage and other exposed areas. 

What is Oiling? 

Oiling is exactly what it sounds like. It’s an oil-based substance that coats your vehicle’s underside, repelling anything water-based that the road throws at it to protect it from rust and corrosion. Oil undercoating is extremely thin (think one sheet of paper) and needs to be reapplied at least annually in order to remain effective. 

While it may seem like a more inexpensive option at a glance, results aren’t guaranteed to last 365 days, and this service will have to be redone completely each year at full cost with little to no warranties available to safeguard the investment you’ve made in your vehicle.  

What is Ziebart Rust Protection?

The best way to protect your car or truck from the damage brought on by rust is to have Ziebart rust protection applied to your vehicle. This will ensure that the vulnerable areas of your vehicle including the trunk, hood and all body panels are sealed. A thick, abrasive-resistant sealant is also applied to your vehicle’s undercarriage, protecting its most exposed areas from moisture, dirt, salt and more.  

At Ziebart, we offer a National Limited Full-Repair Warranty for our rust protection service. 

What is Ziebart Undercoating? 

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.

What are you Waiting for?

Your corrosion warranty usually expires just about the time a vehicle begins to rust through. Most factory warranties only last five years and do not even cover damage caused by road salt.

Salty winter roads can have devastating effects on your vehicle. Even the advanced, galvanized steel used in cars and trucks today is susceptible. There are thousands of spot welds and seams that provide a foothold for rust. 

Whether your vehicle is new or used, Ziebart has options to help protect your vehicle from rust. In fact, we’ve been doing just that for over 60 years. You don’t want to wait for the damage to be done to realize you should’ve had it protected long ago. Contact your local Ziebart store today to help keep your vehicle around longer while preserving its value.
