Choosing the Right Automotive Paint or Primer
When it's time to paint or repaint your car, truck, or motorcycle, choosing the right paint products is key to achieving a professional, long-lasting finish. With so many types of automotive paints and primers on the market, it can be confusing to know which ones to select for your DIY paint job.
Types of Automotive Paint
There are three main types of automotive paint:
- Primer - Provides a base layer that allows paint to adhere to the surface. Primers also smooth out imperfections.
- Basecoat - Contains the color pigments and special effects like metallic flakes or pearls. Basecoat is applied after the primer.
- Clear Coat - A transparent, protective layer applied after the basecoat that provides a smooth, glossy finish.
Primers
Primers are essential for any paint job to succeed. Here are the most common types of automotive primer:
- Self-etching Primer - Bonds directly to bare metal surfaces without needing sanding. Quick and convenient for spot priming.
- High-Build Primer - Can be applied thick to fill scratches or imperfections in the body work.
- Epoxy Primer - A durable, corrosion-resistant primer ideal for metals.
- Primer Surfacer - Sands easily to create an ultra-smooth finish for your top coat.
Matching Paint Colors
When repainting a vehicle, you'll need to match the existing factory color. Here are some tips:
- Find your car's color code, usually located on a sticker in the door jamb or under the hood.
- Use touch-up paint bottles that match your factory color code.
- Get paint mixed to match at an auto paint store with the help of a paint code lookup system.
- For custom colors, supply paint chip samples for the store to scan and match.
Brand and Quality Considerations
Not all paint brands deliver equal results. Here are some good options to look for:
| Brand | Known For |
|---|---|
| Dupli-Color | Match factory colors; easy to apply |
| Rust-Oleum | Affordable, high-quality finishes |
| SEM | Pro-grade paints and clear coats |
| PPG | Industry leader; premium paints |
Buying quality paint from the start will help you achieve better, long-lasting results and avoid frustration over multiple coats and touch-ups.
The Bottom Line
By selecting the right primers, basecoats, and clear coats for your specific automotive paint project, you'll be well on your way to a professional, eye-catching, durable finish you can be proud of.

Primers
Primers provide a base layer that allows paint to adhere properly to the surface. There are several specific types of automotive primer:
- Self-Etching Primer - Contains acids that "etch" the metal surface to create bonds for adhesion. Often used for small spot priming jobs, like priming over bare metal repairs.
- Urethane/Epoxy Primer - A durable, corrosion-resistant primer that provides excellent protection for metal. Ideal for full car priming jobs.
- Primer Surfacer - Sands easily to create an ultra smooth surface for paint. Acts like a thick primer and filler in one.
- High-Build Primer - Applied thicker to fill scratches, imperfections, and uneven surfaces in body work.
Basecoat Paint
The basecoat contains the pigments that provide color. Some types of basecoat include:
- Single Stage Enamel - Balances paint and gloss in one layer without a clear coat. Not as much depth but good for quick jobs.
- Acrylic Enamel - Modern acrylic-based paint that provides a durable, factory-quality finish.
- Metallic/Pearlescent - Contains aluminum flakes or pearl compounds to create special effects.
- Solid Color - Contains no metallic or pearl elements, just pure pigment for a solid color.
Clear Coat
Clear coat is a transparent layer applied over the basecoat that provides a deep, glossy finish. Types include:
- 1K Clear Coat - Single component, easy to apply. Provides decent gloss but less UV resistance than 2K.
- 2K Clear Coat - Two components (paint & catalyst) create a harder, more durable finish.
- Acrylic Urethane - Tough and UV-resistant for long-lasting gloss.

Shop Examples
Here are some real-world examples of how paint types are used:
- A mechanic priming over exposed metal on a fender repair might use a self-etching primer for quick adhesion.
- A custom motorcycle paint job would start by applying an epoxy primer, followed by a metallic basecoat, then a high-grade 2K urethane clear for maximum gloss and protection.
- For a DIY budget paint job, applying Rust-Oleum primer, followed by an enamel single stage paint provides decent results at low cost.
Proper selection of primers, basecoats, and clear coats allows for great looking, long-lasting automotive paint jobs. Consult a trusted paint retailer if unsure about product selection.
Matching Paint to Your Vehicle's Color
When it's time to touch up paint chips or repaint part or all of your vehicle, getting an accurate color match is crucial for a seamless, professional looking finish. Here are some tips on matching your car, truck or motorcycle's factory paint color.
Locate the Color Code
Every vehicle has a paint color code assigned by the manufacturer. This code is key for matching the original color. The code can often be found:
- On a sticker inside the driver's door jamb
- Under the hood on the radiator support or strut tower
- In the owner's manual or glove box paperwork
The code will be a combination of letters and numbers, like WA8624M. Write down or photograph the full code for reference.
Obtain Touch Up Paint
Many automotive paint brands sell small bottles of touch up paint matched to factory color codes. With the code, you can look up and purchase the exact matching touch up paint.
Take Paint Chip Samples
For more significant paint jobs, it's best to bring physical color chip samples to an auto paint store. Use masking tape to capture paint chips from various areas on your vehicle, then bring them for scanning. Scanning determines the precise paint color formulation.
Mixing Custom Paint
For custom or difficult colors, the paint store will scan your samples and use color matching software to recreate the paint. This accurately mixes pigments to match the color chips.
Test Your Match
Before committing to a full paint job, test your color matched paint on a small hidden area of the vehicle. Allow to fully cure, then evaluate the match in both direct sunlight and shade.
Allowing for Fade
If your vehicle's original paint has faded from years in the sun, the new paint won't be an exact match. In such cases, request that the paint store makes an adjusted formulation to allow for fade over time.
Professional Help
For antique, classic or rare vehicles without accessible color codes, your best bet is to work with a professional auto paint color match company. They can analyze the layers of paint and determine the closest match.
With the right preparation and diligence, you can achieve a factory quality color match and paint application on your treasured vehicle.
Differences Between Primers, Basecoats, and Clear Coats
When repainting a vehicle, it's important to understand the distinct purposes and characteristics of the three main types of automotive paint layers: primer, basecoat, and clear coat.
Primer
Primer is the first layer applied to create a bonding surface for the other paint layers. Primer:
- Adheres to bare metal, plastic, fiberglass, body filler, old paint, etc.
- Smooths over imperfections in the surface.
- Is available in gray, white, red oxide, black shades.
- Types include self-etching, urethane, epoxy, primer-surfacer.
Basecoat
The basecoat contains the pigments that give the paint its color. Basecoat:
- Goes on after the primer layer.
- Comes in solid, metallic, pearlescent, and custom mixes.
- Usually requires a clear coat to protect and gloss.
- Can be single stage (paint & gloss combined).
Clear Coat
Clear coat is a transparent layer that goes over the base color. It provides:
- A deep, glossy, protective finish.
- Enhances the basecolor without affecting the hue.
- A smooth surface and a "wet" painted look.
- UV resistance to prevent fading and oxidation.
Process Summary
The typical paint process is:
- Wash, sand, and prime the surface.
- Apply colored basecoat in 2-3 coats.
- Allow basecoat to dry.
- Apply 2-3 coats of clear gloss protective coat.
- Wet sand and buff clear coat for a polish.
Following these paint layering steps with the proper prep work will result in a professional, durable, and great looking automotive paint finish.
Paint Glazes, Additives, and Activators
In addition to primers, basecoats, and clear coats, there are other important paint products to consider when painting a vehicle:
Paint Glazes
Glazes are used after the color coat to help smooth and fill minor imperfections in the paint before clear coat is applied. Benefits include:
- Fills in dust specks and orange peel.
- Levels out minor scratches and sanding marks.
- Creates an ultra-smooth surface for the clear coat.
- Easy to apply by hand or machine polisher.
Paint Additives
Additives can enhance certain properties of the wet paint or finished coating:
- Flex Additive - Improves flexibility to prevent cracking on plastic/flexible parts.
- Texture Additive - Provides a textured, orange peel look.
- Fish Eye Eliminator - Prevents imperfections caused by contamination.
- Accelerator - Speeds up drying time.
Activators
Activators start the chemical reaction that turns paint from liquid to solid on the surface. Types include:
- Catalysts - Used with 2-part paints to start the curing process.
- Hardener - Speeds up cure time and increases gloss.
- Thinner - Lowers paint viscosity and slows drying.
Uses
Some examples of use:
- Adding flex agent to paint for bumpers prevents cracking.
- A paint glaze creates an ultra smooth finish on a classic car.
- A faster activator allows paint to be recoated sooner.
Talk to your paint retailer about which additives and activators will be helpful for your specific automotive paint project needs.

Protecting Your Vehicle With High-Quality Automotive Paints And Primers
Automotive paints and primers are essential for protecting your vehicle's exterior from environmental hazards such as rust, moisture, and water damage. Automotive primer acts as a base layer and helps protect the car's body from water, rust, and other environmental hazards. It also serves as a bonding agent to help the paint adhere more strongly to the body of the vehicle. Equally important, paint primer helps prevent rust and moisture damage to your vehicle by adding a couple of extra protective layers. Automotive primer sealer, like urethane or epoxy-based, can also serve as a filler for sanding/grinding marks and small scratches on your car body, negating the need for putty or a more prolonged repair job, like a urethane surfacer. The kind of car paint primer you end up using will vary with your project needs. Before buying primer and paint, it is recommended to check with your local automotive paint shop to ensure that the products are compatible. The first and most important step when applying primer is to get the body's surface ready first. Use compressed air to remove all dust and dirt from joints and recessed areas, then wipe the entire car down with wax/silicone remover.
