Graphene Ceramic Coating: Is It Better Than Ceramic?

What is a graphene ceramic coating?

Graphene is a sheet of carbon just one atom thick. Its atoms link up in a honeycomb pattern. In the lab, pure graphene is very strong and moves heat well.

A car coating is not a sheet of pure graphene, though. Most graphene coatings for cars are ceramic-type coatings. That means a clear liquid that hardens into a thin, tough shell on the paint.

A small amount of a graphene-based material, often a form of graphene oxide, is added to that liquid. So the base coating still does most of the work. The graphene is a helper, not the main ingredient.

The label may not say how much graphene is in the bottle. That is worth asking about, as you will see below.

Graphene vs ceramic coating: is graphene better?

Not in a simple way. Most graphene coatings are ceramic coatings with one extra ingredient. So the real question is whether that ingredient helps on your car.

Here is what graphene may change. Makers say it adds slickness, so dirt slides off more easily. They also say water beads up or sheets off faster.

Those claims can be true for a given product. But a well-made ceramic coating with no graphene can be just as slick. The label alone does not tell you which will do better.

Some people say graphene makes paint look deeper or darker. Most of that look comes from the paint under the coating. Clean, swirl-free paint shines more with any coating on top.

Do graphene coating claims hold up?

This table puts each common graphene claim next to what a good plain ceramic coating does.

A good rule: if a claim has no date and no test details, treat it as marketing. That goes for any coating, not only graphene.

What doesn't graphene change?

Some things decide how long a coating lasts, no matter what is in the bottle. Graphene does not let you skip any of them.

• Prep. The paint must be washed, decontaminated and clay barred first. A clay bar is a soft clay that pulls stuck grit off paint.
• Paint correction. This is machine polishing that removes swirls and light scratches. Any flaw left on the paint gets sealed under the coating.
• Panel wipe. This spray strips polish oils so the coating can bond to bare paint.
• Cure time. Our coatings stay dry the first night and go unwashed for 10 to 14 days.
• Wash method. Use a hand wash or touchless wash only. Brushes in a tunnel wash can mar any coating, and they void our coating warranty.
• Upkeep. A coating needs gentle washes and a yearly check-up. Our warranty requires a yearly Ceramic Maintenance Detail.
• Real limits. No coating stops rock chips, key scratches or door dings. For chips, you need paint protection film.

Is a graphene coating worth the extra money?

Graphene products are often priced higher than plain ones. The extra cost is only worth it if it buys something real. That could be better prep, a longer tier or clearer warranty terms.

Use these questions on any product or installer. Clear answers are a good sign. Vague answers are a warning.

• What is the base of the coating, and how much graphene is in it?
• How many years is it rated for, and who tested that?
• What prep is included? Is paint correction part of the price?
• How long do I wait before the first wash?
• Which wash methods are allowed? Does a tunnel wash void the warranty?
• Is a yearly upkeep visit needed to keep the warranty?
• Does the warranty move to the next owner if I sell the car?
• Can one panel be fixed or topped up if it gets damaged?

Graphene spray vs full graphene coating: which do you need?

You will also see graphene sprays and spray coatings at auto parts stores. They are easy to use. They add gloss and slickness, but they wear off much sooner than a true coating.

A spray is a nice topper for a car you wash yourself. It is not a stand-in for a full coating with prep. If you want to try one at home, it is easy:

• Wear nitrile gloves, work with good airflow and follow the label.
• Wash the car and dry it fully with clean microfiber towels.
• Work in the shade on a cool panel. Never spray onto hot paint.
• Mist one panel at a time. A little product goes a long way.
• Spread it with one towel. Then buff it off with a second, clean towel.
• Check for streaks from a few angles before you move on.
• Keep the car dry for as long as the label says.

Does graphene help with Bay Area fog and salt air?

Bay Area paint deals with fog, salt air near the water and lots of street parking. Any good coating helps here. It keeps salt and grime from sticking hard, so rinsing is easier. That is true with or without graphene.

Water spots are a separate topic. San Francisco tap water is soft. Most spots here come from water drying on warm paint. Sprinkler overspray and fog that the sun dries later cause them too. A slick coating sheds more water, but no coating stops every spot.

Good habits do more than any added ingredient:

• Parked near the water in the Marina, Sea Cliff or Sausalito? Rinse off salt film often.
• Parked under trees? Remove sap and bird droppings fast. They can etch even coated paint.
• Just got a new coating? Keep it in a garage the first night if you can, so fog and dew stay off.
• Rain season? Rain leaves dirty drops behind as it dries. Once the 10 to 14 day cure is over, a gentle hand wash after a storm clears them.
• No hose at your apartment? Our van brings its own water and power, so we can hand wash a coated car where it is parked.

How should you choose a graphene or ceramic coating?

Choose by durability tier and prep, not by the word graphene. A longer tier costs more, and it still needs good prep to last.

Here is how our ceramic coating tiers work. These are starting prices. The final quote depends on your paint's condition.

• From $799: a 2 to 3 year coating with 1-step paint correction included.
• From $1,499: our 6-year tier.
• From $2,499: our flagship tier.
• SUVs and trucks add $200 on any coating.
• A yearly Ceramic Maintenance Detail ($250 sedan, $300 SUV) keeps the warranty active. The warranty does not transfer if you sell the car.

When should you call a pro for a coating?

Call a pro if you can see swirls on your paint in the sun. Call one if you want a coating to last for years, or if you have no garage or polisher. Those are the jobs where prep makes or breaks the result.

Our technicians come to your home, office or apartment garage in San Francisco, the Peninsula and Marin. Coating installs also reach Palo Alto and parts of the East Bay. A coating takes a full day, so we book it ahead.

If you have a graphene product in mind, tell us when you ask for a quote. We will explain honestly how it compares to our tiers.
