Clear coat is the colorless top coat that is applied over the colored paint on a vehicle either when it is repainted, or as a way to rejuvenate and protect the existing paint. There are usually at least 2-3 coats of clear coat applied in order to protect the paint from sun and other damage. Avoid driving the car until the paint is fully dry, which should take about 24-48 hours. The paint will be fully cured after 30 days.

What is Clear Coat?
Clear coat is sometimes also called a top coat. You may also see it referred to as two-stage paint. This is because it is the second stage in the car painting process. Alternatively, clear coat can be applied to a car in order to bring new life to old paint.
Definition of Clear Coat
Simply put, the clear coat is the clear top coat that is applied on top of the colored paint on a vehicle. Typically, a car needs at least two layers of clear coat, but three or more is considered ideal, so the car can be buffed, if necessary.
Purpose for Clear Coat
The main reasons to apply clear coat to a vehicle are:
- Protect the paint from ultraviolet (UV) rays.
- Provide a protective layer to save the paint from scratches and scuffs.
- Give the car a shiny finish.
- Cover and fill in minor scratches that may mar the existing paint.
Clear coat can be applied either as the last step in a painting process or as a restorative step to protect and enhance the paint on a car. It may be helpful to apply clear coat to a car before trying to sell it. Clear coat can enhance the car’s appearance and help boost resale value.
How Long Does It Take for Clear Coat to Dry?
Clear coat will be dry to the touch within 24-48 hours after application, depending on various conditions. However, be careful! It is still considered soft at this point and could be easily damaged. Avoid gravel roads or driving near construction vehicles that could fling debris at your car.
How Long Before I Can Drive the Car?
It’s best to wait at least 48 hours after the clear coat is applied before driving the car. Avoid driving in areas, such as gravel or construction zones, that could damage the clear coat before it is fully cured.
The clear coat may take up to 30 days to fully cure and harden. Avoid anything that could scratch or smudge the clear coat during that time, and do not wash the vehicle.
What’s the Difference Between Drying and Curing?
When you hear about paint drying time, you may also hear about curing. Are drying and curing the same thing? Does one take longer than the other?
If the paint is considered dry, that means it is dry to the touch. It doesn’t feel tacky or sticky any longer. Typically, for a clear coat, this takes about 24-48 hours, depending on environmental conditions. At this point, the vehicle is driveable.
It is important to know that the paint is dry, but it is still soft. If you press your fingernail into it, it will leave an imprint. There are still solvents present in the clear coat that need to fully evaporate before the paint is completely hard. That is why it is important to babysit your vehicle until the paint is fully cured.
Curing occurs when all the solvent has evaporated from the paint and the paint reaches optimum hardness. For most clear coats, this takes about 30 days, but it could take as long as 90 days. Proper curing is important to make sure the clear coat lasts a long time and looks its best.
If at all possible, store the vehicle indoors while the clear coat and paint are curing. Prolonged sun exposure should be avoided during the month after application. Also, avoid parking under trees. Bird waste can damage the paint and clear coat, or trees can drop berries and debris on the vehicle.
What Affects Drying Time?
Many factors affect the drying time for a clear coat. Most of these factors are environmental, though the type of paint and the application process can affect drying time too.
Check the Temperature
Clear coat will dry faster in higher temperatures. For optimal results, wait to paint a vehicle until the temperature is at least 60 degrees Fahrenheit, or 15 degrees Celsius.
As the temperature gets colder, then paint and the clear coat will take longer to dry. If the temperature is below 60 degrees, expect the drying time to double or possibly triple if the temperature is really low.
Watch out for Humidity
The level of moisture in the air directly affects drying time. Moist, humid conditions will cause the paint to dry slower because the moisture in the paint will not evaporate as quickly. On the other hand, dry conditions will allow the paint fumes to evaporate more quickly and the paint will dry faster.
Avoid applying vehicle paint or clear coat if there is rain in the forecast or high levels of humidity. Wait for a dry, clear day to paint with humidity levels below 50 percent.
Avoid Sun Exposure
Heat and warmth can speed up drying time for a clear coat. However, the ultraviolet rays of the sun can damage the clear coat and paint before the clear coat is fully cured.
One of the roles of a clear coat is to protect the vehicle’s paint from UV rays. If you have at least two to three coats of clear coat on the car, the paint will be protected from fading and cracking due to the sun once the clear coat is cured.
Be Mindful of Wind
Just like a breeze can help dry laundry on a line, a light breeze can also make a difference in drying time for a clear coat. However, wind or a fan may also blow dust right into the sticky clear coat!
Check Your Materials
Different varieties of clear coat dry at different speeds. For an ultra-quick drying clear coat, look for a clear coat that has a thin consistency. In general, if you need the clear coat to dry fast, look for a paint that says “Quick Drying Formula”.
How Soon Can the Car be Washed After Clear Coat is Applied?
It’s best to wait to wash the car until the clear coat is fully cured or at least 30 days. Some technicians even recommend waiting 90 days before a car wash!
Wait to wash the car because the soap reacts with the solvents in the clear coat. Once the clear coat is cured and the solvents are all evaporated, it is fine to wash the vehicle. Also, avoid waxing uncured clear coat. The wax can cause the clear coat to look cloudy.
How Can I Make Clear Coat Dry Faster?
If you are looking to speed up the process, here are a few tips!
Apply in the Right Weather
Applying clear coat in optimal weather is the best way to help it dry. Look for a day when it is dry and above 60 degrees Fahrenheit.
Utilize Indirect Air Flow
Indirect air flow will also help the clear coat dry faster. Don’t point a fan directly at the vehicle, or it may cause dust to stick to the paint.
Heat It Up
Heat will help the clear coat dry faster. In fact, some auto body shops bake vehicles in order to speed up the drying process. A space heater or a heat gun can be helpful to get that clear coat dry.
Which Top Coat Dries the Fastest?
Glamour Aerosol Clear Coat is a highly rated, quick-drying paint that also has good weather resistance.

Use a clear coat to give your car’s paint a new life! Clear coat protects against scratches and UV damage and helps your car look glossy and new again. Make sure to follow the package instructions. Typical drying time is 24-48 hours, but remember that the paint won’t be fully cured for at least 30 days, so drive with caution!
