Factory Paint Codes And Specifications For Nissan 240sx Models In Black

Alright, let's dive into the fascinating, and sometimes frustrating, world of factory black paint codes for the Nissan 240SX. If you're repainting, touching up, or even just trying to match the original finish after some body work, knowing this information is absolutely critical. This guide will focus specifically on the black paint options available across the S13 and S14 chassis. Be prepared for some code deciphering!

Understanding Paint Codes and Their Significance

Before we jump into specific codes, let's clarify what a paint code actually *is*. It's essentially an alphanumeric identifier – a short sequence of letters and/or numbers – that uniquely specifies a particular paint formula. This formula dictates the exact pigments, binders, and other chemical components used to create a specific color. Manufacturers like Nissan use these codes for precise consistency across their production lines. Without it, you'd have a whole lot of slightly-off 'black' cars rolling off the assembly line. Using the wrong paint code will result in a mismatch, something you definitely want to avoid, especially when dealing with metallic or pearl finishes.

The paint code is typically found on a VIN (Vehicle Identification Number) plate, usually located in the engine bay on the firewall, or sometimes on the driver's side door jamb. The exact location can vary slightly depending on the year and specific model.

Key Paint Components to Consider

When talking about automotive paint, it's important to be familiar with a few key components:

Basecoat: This is the colored layer that provides the actual hue. For black cars, this is where the specific black pigment resides.
Clearcoat: This is the protective top layer that provides gloss, UV protection, and chemical resistance. It's what makes your car shiny and helps prevent the basecoat from fading.
Primer: The undercoat applied to the bare metal to promote adhesion and provide a uniform surface for the basecoat. While not technically part of the "color," selecting the correct primer color (usually grey or black) is crucial for achieving the correct final color appearance, especially with darker colors.

Black Paint Codes for S13 (1989-1994) 240SX

The S13 chassis saw a couple of different black paint options throughout its production run. Let's look at the most common:

KH3 - Super Black

This is arguably the most prevalent black offered on the S13. KH3, often referred to as Super Black, is a solid, non-metallic black. This means it doesn't contain any metal flakes or pearlescent pigments. Because of its simplicity, it's generally easier to match and touch up than metallic paints.

Technical Details: Super Black is a single-stage paint system, although modern repairs often incorporate a clearcoat for enhanced durability and UV protection. A single-stage system means the color pigment and the clear binder are combined in a single layer. However, due to modern environmental regulations and the desire for improved durability, almost all shops apply a separate clear coat even when using a single-stage formula for the color layer. The formula for KH3 involves specific ratios of black pigments and acrylic binders. The exact formulation details are proprietary to paint manufacturers, but it's important to use a high-quality automotive paint specifically designed for exterior applications.

Touching Up: Given its non-metallic nature, KH3 is relatively forgiving when it comes to touch-ups. Small imperfections can often be blended successfully with proper technique. However, larger areas will require more careful attention to ensure a seamless match. Always use a primer recommended for your chosen topcoat and follow the manufacturer’s application guidelines.

AH3 - Dark Gray Metallic (Rare)

While not technically "black," it's dark enough that it is commonly mistaken for a dark black depending on lighting and the overall condition of the paint. AH3, or Dark Gray Metallic, does have metallic flakes mixed in. Because of this, the overall color will change depending on the viewing angle. This makes it a much more challenging color to match when doing repairs, so it's vital to know what the original paint code for your car is.

Technical Details: This paint code utilizes a 2-stage system. AH3 contains fine metallic flakes that reflect light, giving it a subtle shimmer. The clearcoat is extremely important as it protects the metallic particles and influences the overall reflectivity of the paint. Any variations in the clearcoat application (thickness, texture) will be immediately noticeable.

Touching Up: Metallic paints are notoriously difficult to touch up flawlessly. The key is to apply very thin layers and blend carefully. You may want to consult a professional for larger repairs as getting the metallic flake alignment and distribution correct is tricky. Make sure to use the correct clear coat to match the sheen.

Black Paint Codes for S14 (1995-1998) 240SX

The S14 continued with variations of black, again with some subtleties. Again, knowing the *exact* paint code is crucial.

KH3 - Super Black (Continued)

Nissan continued to use KH3 - Super Black on the S14. The formulation remained largely the same, although slight variations may exist depending on the paint manufacturer. However, it's generally considered to be a close enough match that KH3 from different manufacturers can be used interchangeably for minor touch-ups. Always test a small, inconspicuous area first.

KG1 - Jet Black

KG1, often called Jet Black, is another solid black option, and is somewhat less common than KH3. There is a slightly different undertone compared to KH3, which is hard to see without looking at paint chips side-by-side.

Technical Details: Like KH3, Jet Black is generally considered a single-stage paint, though applying a clearcoat for protection is common practice. The difference between KG1 and KH3 comes down to the specific black pigments used in the formulation and the subtleties of the binders. The effect of UV on this color may be different from KH3.

Touching Up: Similar to KH3, KG1 is easier to touch up than metallic paints. Ensure you use the correct primer and clear coat if using a two-stage paint system.

Finding Your Paint Code and Ordering Paint

As mentioned earlier, the paint code is typically located on the VIN plate. Look for a section labeled "Color Code" or something similar. It's usually a short code consisting of two or three characters. Once you have the code, you can order paint from various sources:

Automotive Paint Suppliers: These are specialized shops that sell automotive paint, primers, clearcoats, and related supplies. They can often mix custom batches of paint based on the factory code. They can also help you understand the various paint systems and recommend the best products for your specific needs.
Online Retailers: Many online retailers sell automotive paint, but be cautious. Ensure they offer a color matching guarantee and a reputable brand. Read reviews carefully before ordering.
Dealerships: You can sometimes order touch-up paint or even larger quantities of paint through a Nissan dealership. However, this is often the most expensive option.

Important Considerations When Ordering:

Paint System: Decide whether you want a single-stage or two-stage paint system. A two-stage system (basecoat/clearcoat) offers better durability and UV protection, but it's more complex to apply.
Paint Type: Choose between lacquer, enamel, or urethane paints. Urethane paints are generally considered the most durable and offer the best resistance to chemicals and UV radiation.
Quantity: Calculate how much paint you'll need based on the size of the area you're painting. It's always better to have a little extra than to run out.
Clearcoat and Primer Compatibility: Ensure that the clearcoat and primer you choose are compatible with the basecoat. Mixing incompatible products can lead to adhesion problems and other issues. Follow the manufacturer's guidelines carefully.

Tips for a Successful Paint Job

Whether you're tackling a small touch-up or a full respray, here are a few tips to help you achieve professional-looking results:

Preparation is Key: Thoroughly clean, sand, and degrease the surface before applying any paint. Remove any rust or corrosion.
Use Proper Ventilation: Always paint in a well-ventilated area and wear appropriate safety gear, including a respirator and gloves.
Apply Thin Coats: Avoid applying thick coats, which can lead to runs and sags. Apply several thin coats, allowing each coat to dry properly before applying the next.
Maintain Consistent Distance and Speed: When using a spray gun, maintain a consistent distance from the surface and move at a steady speed to ensure even coverage.
Wet Sanding: After the clearcoat has dried, you can wet sand it with fine-grit sandpaper (e.g., 2000-grit) to remove any imperfections and create a smooth surface.
Buffing and Polishing: After wet sanding, use a buffing compound and a polishing compound to restore the shine and gloss to the paint.

Matching factory paint, especially on older cars, can be challenging. UV exposure and other environmental factors can cause the paint to fade or change over time. Even with the correct paint code, the new paint may not be an exact match to the existing paint. In these cases, blending the new paint into the surrounding areas can help to minimize the difference.

Working with automotive paint requires patience, attention to detail, and a willingness to learn. However, with the right knowledge and techniques, you can achieve impressive results and restore your 240SX to its former glory.
