What to Look for in a Ceramic Coating

Durability

Some coatings advertise years of durability, while others offer only months.

Water Behavior

Some coatings exhibit “beading” hydrophobicity, while others “sheet” water off the paint.

Chemical Resistance

Higher-end, pro-style coatings offer protection against etching contaminants.

Surface Type

Some ceramic coatings are designed for glossy clear coat, while others are designed for matte finishes or PPF/vinyl.

What Ceramic Coating Should I Use?

There are a ton of different ceramic coatings on the market. Some are harder to use and some are more forgiving. Some are thick and some are thin. Some bead water, others sheet it. If you’re doing this yourself, choosing the right coating matters. Here’s what to look for.

BASIC CERAMIC COATING PROCESS

Apply

Applying ceramic coating

Divide large panels into smaller sections. Apply the coating to one small area at a time, crosshatching and overlapping by 50% to get full coverage.

Level

Leveling ceramic coating

Look for flashing. Once the coating has flashed, wipe with a clean microfiber towel to level the coating, then flip the towel and buff to remove excess.

Inspect

Inspecting ceramic coating

Use an inspection light to check for high spots. Use a fresh microfiber towel to re-level any visible high spots, then repeat the process across all sections.

Caution – High Spots May Occur
High spots are areas where the coating hasn’t been fully leveled that can only be removed by polishing once the coating is cured. Be sure to always inspect for high spots after applying and re-level if any are found.
1 Hour

Initial Set-Up

Coating bonds with the clear coat. Leave vehicle undisturbed for one hour following application.

24-48 Hours

Initial Cure

Coating begins to cure. Avoid water exposure during first 24–48 hours after application.

1-2 Weeks

Full Cure

Coating continues to cure. Avoid washing during first week to two weeks.

Caution – Avoid Automatic Washes
Once the coating is cured, DO NOT use automatic washes to clean your car’s paint. The harsh chemicals and abrasive bristles will reduce your coating’s lifespan significantly through premature wear.

How Long Does it Take For Ceramic Coatings to Cure?

You can’t drive the car for at least an hour. You can’t get it wet for 24 to 48 hours. You definitely can’t wash it for at least a week. These are all things you’re told not to do while your ceramic coating is curing. But how long does that curing actually take, and what happens if you don’t follow the rules? Let’s explain.
