How to Protect Car Paint and Your Car’s Undercarriage

The fresh coat of wax on this sports car will protect car paint.

Car paint isn’t just there to look good. It’s what keeps the metal underneath from being exposed to rust. Here are three easy ways to protect car paint, so it protects your vehicle longer, and one way to ensure your undercarriage also gets the love it deserves.

1. Keep It Clean

Wash your car regularly and often. It’s the first and easiest way to protect car paint. That’s not just dust that builds up on your car when you go too long without a wash. It’s tree sap, road grime, bugs, leaves and pollution … any and all of which can fade, discolor and even eat your paint away.

Washing your car is a great do-it-yourself project, and there’s a wide array of washes, cloths and complete kits that can help you give your car a professional-quality wash at home.

2. Work Wonders With Wax

Once you’ve cleaned your car, it’s essential to protect its paint from future damage. That’s where car wax comes in. Wax puts a barrier between your paint and the elements, while enhancing your car’s shine. Car wax comes in pastes and easier-to-use liquids, and applying it is another job that you can easily do in your own driveway.

3. Block the Sun

Just like your skin, the sun can harm the finish of your car. Instead of burning, though, it’ll fade. There are a few ways to protect car paint from the sun, like simply parking indoors, or using a car cover. If you don’t have access to indoor parking, there are many different types of covers, including ones that lock.

4. Don’t Forget the Undercarriage

Nobody is suggesting you should wax the undercarriage of your car, though some classic and show cars do get that treatment. But shouldn’t you give the essential mechanical and structural parts of your car — like the floorpan, wheel wells and suspension — some tender, loving care, too?

The objective here is pretty much the same as protecting car paint. It’s to remove dirt and debris that contains elements that can corrode coatings and encourage rust. After a good wash, applying undercoating to a clean undercarriage can help protect your vehicle.

Most of these tips you can do at home, but if you’re not comfortable with getting under your car, or aren’t sure you know what you should and shouldn’t be undercoating, you may want to consult a professional. Whichever method you choose, make sure you protect your car’s paint, so it protects vital components from the elements.
