Single Stage vs Two Stage Paint – What’s The Difference?

Published: 09/14/22 •  9 min read

Single-stage paint and two-stage paint are the primary methods of painting cars. Classic cars have used single-stage paint jobs for many years. The single-stage color was prevalent in Japanese automobiles in the 1980s and the 90s. Non-metallic colors such as black, white, and yellow were usually single-stage. These paints were less complicated and more difficult to scratch than modern vehicles, with more durable clear coats. 


What is Single Stage Paint?

Single-stage paint involves all the chemicals in the mix to finish the car painting process in one go. It eliminates the need for a clear coat on top. This type of paint is often used on classic cars and can be repainted to get the right look.

What is Two-Stage Paint?

Two-stage painting involves a base coat, over a primer, for the color. Then, a clear coat is applied. Initially, the base coat is flat and shines when a clear coat is applied.

Difference Between Single Stage Painting and Two-Stage Painting

The difference between single-stage and two-part paint is as simple as it sounds. Single-stage coatings should be applied after priming your car. The clear coat is not necessary because the base coat has glossy ingredients. Once you are done, you can remove the primer. 

Two-stage paints separate the color and clear coat, giving your car a transparent finish that is more visible than single-stage paint. It provides uniform color coverage and is applied after the primer stage, and has a matte, dull look. The final step is to apply a clear coat to give the translucent layer and shine.

Single Stage Paint Durability

The main reason for painting the car is safeguarding it from damage due to elements. Thus, “more” is better. 

The durability of single-stage paint sucks. It doesn’t have a long life in comparison to two-stage paints. It is not possible to be protected from the elements by using just one-stage paint like a two-stage base coat/clear coat.

There’s only one layer that can safeguard your vehicle from what’s beneath. You likely have a primer layer underneath the paint, but if the paint layers wear out, it won’t be enough to shield your car from the harm it could suffer from rain, sun, salt, and snow. You will notice cracks, fissures, and oxidation of the paint.

What is Better – Single Stage or Two Stage Paint?

Single-stage paint dries to a glossy appearance and does not require a clear coat. In contrast, the base coat, also known as the clear coat and base coat, is dried to a semi gloss or matte appearance. The next coatings of the clear coat make it shine. 

Which is the better one? In terms of the quality, both are great. It’s all about the color you prefer. If you are looking for a simple red or black or something else you want, you can save some money and time by choosing a single-stage color. You don’t need a clear coat. 

You can find some in the single-stage form if you are looking for metallic finishes; however, you might be better off with a base coat or clear coat method. The two-stage pai

nt process requires that the base coat be layered with a clear coat. Base coats can’t withstand the elements. To enhance protection and add depth, you will need to apply a clear coat. The additional layer protects against chips and scratches, and it allows for more wet sanding for a silky smooth gloss. 

If you think of something wilder, like pearl or metal flake, it is essential to utilize a base coat or clear coat because the pearl and metal flake treatments are sprayed between the clear coat and the color.

Single Stage Paint vs. Base Coat/Clear Coat

The significant distinction between single-stage paint and base/clear is the process of painting. Once the paint is put on a car, it is just two minor differences that could be noticeable to the average car owner:

  1. Single-stage paint is more likely to be in the process of oxidation if left in the sun unprotected for a prolonged amount of time. When oxidized, it has a highly dull, chalky appearance and feel. For example, if you find a vehicle with a pink color that was once red, it’s a single-stage paint that’s not protected. A clear coat can be oxidized, but it’s not apparent to the eyes. The reason is that the coat is transparent. Therefore, if it becomes dull, white, or cloudy, the contrast between what it looks like and how it ought to appear isn’t that much of an impact. 
  2. Single-stage paint bleeds color on polishing towels and pads or anything else that functions for abrasive purposes. 

Orange Peel

Nothing is more frustrating than getting an uneven, textured appearance when you spray paint your car. The most common term used to describe this appearance is orange peel.

It is usually the result of a wrong paint technique. It is caused by the rapid loss of thinner, improper spray gun configuration (e.g., inadequate air pressure or a wrong nozzle), spraying the paint at an angle different than perpendicular, or using too much paint.

How to Fix Orange Peel?

To fix the orange peel, it is necessary to decrease the particle size being sprayed, known as atomization. You can improve the atomization of your painting by thinning it by increasing the amount of air in your paint, reducing the paint applied at a particular time, increasing the pressure you use in an airless sprayer, or using other tools that can efficiently atomize. These guidelines will help you eliminate the orange peel that you see during painting.

Frequently Asked Questions (FAQs)

What number of layers of clear should you spray over single-stage paint?

You should have three to four layers of protection for the UV rays, dirt, and other impurities your car may come in contact with. Between coats, take breaks. Avoid spraying too much material in wet coats, as this could cause cracking of clear coats.

Can a clear coat be used to restore single-stage paint?

The clear coat is a transparent layer that you apply to your paint. It adds gloss to your paint but does not restore old paint or faded single-stage paint. This is not the purpose of a clear coat. However, you can apply new paint.

What is the best time to clear coat single-stage paint?

Applying a single-stage coat is different from modern two-stage paint, where you first apply a base and then clear. You can apply the mixed-up paint in one stage. Clear coats are not required after the paint has dried. Clearcoat single-stage paints only after it has dried.

Is it possible to clear coat single-stage paint?

Clear urethanes and single-stage urethanes can be sprayed over the top of the clear without mixing. This will enhance the gloss. The clear coat over the top is also a great way to make the gloss look even more vibrant.

How many coats of single-stage paint can I apply?

You can apply two coats of single-stage paint for a perfect look. Moreover, you don’t have to wait for the paint to flash between coats, which usually takes 15 to 25 minutes.

Is Single Stage Paint Better?

Single-stage paint is an excellent option when you are not concerned about appearance and are satisfied with an average shine. However, it would help if you consider the reality that the single-stage finish coat will be exposed to direct the sun and weathering, and it’s likely to dull after some time.

How to Prevent Orange Peel in Single Stage Paint?

It is best to eliminate it at the end of applying the clear coat. You can do this by using a wet sanding process on your paint film’s surface and then polishing using a lightly abrasive polish and a rotary polisher with high speed.

Can I paint over single-stage paint?

Yes, you can apply clear or base over one stage. Make sure to finish the single-stage up to the point where it can paint over it and still look great. The spray job can only be as good as the substrate and the preparation work. Make sure that you remove any dirt that may be there on the car surface.
