Ceramic coatings for your vehicle’s exterior offer a long-lasting alternative to waxes and synthetic sealants. Simply wipe on a ceramic coating after washing your car and get a shine that lasts for years. But is it that easy?

Ceramic Technology

Do-it-yourself ceramic coatings were introduced to the car-care market more than 20 years ago. The main advantage of a ceramic coating is how it makes water bead and roll off the car. The technical term for that is hydrophobic - opens in new window or tab..

The ceramic layer also helps prevent bird droppings and other debris from staining your car. Besides, the ceramic coating gives your car a brilliant shine.

Manufacturers produce ceramic coatings using silicon dioxide (SiO2) and other chemical compounds. When properly cared for, ceramic coatings can last several years. They typically come in two versions: professional and consumer grades.

Professional grade: Providers sell professional-grade coatings primarily to car detailing shops. In some cases, you need a certification to make a purchase. These products are thicker and have a higher ceramic concentration than consumer versions. Applying a professional-grade ceramic requires skills and a long curing time. Pro-grade products often come with a warranty.
Consumer grade: eBay Motors offers a range of consumer-grade ceramic coatings. These contain less silicon dioxide than the pro-level products. Consumer coatings are easier to apply, have a watery feel, and cure faster.

Prep and Application

A ceramic coating can last a few years, so it’s critical that your paint is perfect before applying it. This explains why professionals charge a fee. They might spend days prepping the paint, using a clay bar - opens in new window or tab., and otherwise making it shine before applying the ceramic material.

If you apply the ceramic coating at home, start the process with a thorough wash. Then, use a clay bar - opens in new window or tab. to remove any embedded grime on the paint’s surface. Finally, apply a car polish to level the paint and make it pop.

Before using the ceramic coating, wipe the paint with an isopropyl alcohol - opens in new window or tab. solution to remove any remaining oils and waxes.

Read the manufacturer’s directions thoroughly before starting this job.
Work in a dust-free garage or other enclosed space.
Wear latex gloves - opens in new window or tab. to avoid oil from your hands getting onto the paint.
Apply ceramic coating to one panel of your car at a time.
The ceramic coating sets quickly. Some providers recommend applying the product in a crisscross style (up and down and then left to right), while others ask for the coating to be applied in a diagonal cross-hatch manner.
Some providers recommend two coats or more. If so, use a new applicator with each coat because an applicator hardens after its first use.

After you apply the coating, buff it with a microfiber cloth - opens in new window or tab. to even the coat.

For best results, allow the car’s surface to cure for two days. The ceramic coating dries and hardens over time. If possible, avoid driving the vehicle and keep it in a garage away from dust and contaminants.

Maintenance

Your new ceramic coating won't magically protect the surface from rock chips or prevent swirls from improper washing. Keep your car as clean as possible. Some ceramic kits include a spray to maintain the surface. Professional detailers might require an annual maintenance plan to keep the warranty valid.

Store any unused product in a cool, dark spot.

A Warning About Water Spots

Water beads up on cars with ceramic coatings, which is mostly a good thing. Instead of leaving water lying flat, soak up the beads while drying your car.

Those water beads contain mineral deposits and chemicals. The minerals can etch into the coating if they are left to dry on the surface.

A lot of the water beads will slide off when you drive. However, you should remove all of them with a detailing spray and microfiber cloths. Some companies offer detailing liquids designed for ceramic coatings. Or try a basic detailing spray, like Chemical Guys - opens in new window or tab.
