- Apply a thin, even coat of primer to the plastics using a spray gun or a brush.
- Allow the primer to dry completely before applying the paint.
Applying Paint, How to paint dirt bike plastics
Now that the primer is dry, you can start applying the paint. Remember, thin coats are crucial for a smooth and even finish.
- Apply the paint in light, even coats, allowing each coat to dry completely before applying the next.
- Use a spray gun or a brush for application, ensuring you are working in a well-ventilated area.
- Avoid applying too much paint at once, as this can lead to drips and runs.
- If using a brush, use long, even strokes to avoid brush marks.
- If using a spray gun, maintain a consistent distance from the surface and a steady hand.
Using a Sealant
A sealant protects the paint from scratches, UV damage, and other elements.
- Apply a sealant to the painted plastics after the paint has completely dried.
- A sealant can be applied with a spray gun, brush, or cloth.
- Follow the sealant manufacturer’s instructions for drying time.
Achieving a Smooth Finish
To achieve a smooth and even finish, it is important to use multiple thin coats and allow each coat to dry completely before applying the next.
- Sanding between coats can help to smooth out any imperfections and create a flawless finish.
- Use fine-grit sandpaper for this purpose, sanding lightly and in the direction of the paint flow.
- Avoid sanding too hard, as this can damage the paint.
Drying and Curing the Paint
After applying the paint, allowing it to dry and cure properly is crucial for a durable and long-lasting finish. Improper drying can lead to a weak paint film, prone to chipping, cracking, or peeling.
Drying Time and Temperature
The drying time for paint depends on several factors, including the type of paint, the thickness of the applied coat, and the ambient temperature and humidity. Generally, most acrylic paints require several hours to dry to the touch, but it’s recommended to allow at least 24 hours for complete drying. A warm and dry environment, around 70-75 degrees Fahrenheit (21-24 degrees Celsius) with low humidity, is ideal for drying.
Protecting the Painted Plastics
While the paint is drying, it’s essential to protect it from dust, debris, and insects. These contaminants can become embedded in the wet paint, compromising the finish.
- Cover the painted plastics with a clean sheet or cloth.
- If possible, hang the plastics in a dust-free environment.
- Avoid touching the painted surface until it’s completely dry.
Curing Process
Curing is the process where the paint hardens and becomes fully resistant to scratches, abrasion, and chemicals. While the paint may appear dry to the touch after a few hours, it continues to cure for several days or even weeks. The curing process is influenced by factors like temperature, humidity, and the type of paint used.
The recommended cure time for most acrylic paints is at least 7 days.
Finishing Touches
After applying the paint, the final step in achieving a professional-looking dirt bike plastics paint job is adding finishing touches. These touches not only enhance the aesthetics but also provide protection and durability.

Clear coat is a crucial finishing touch that seals the paint and protects it from scratches, UV damage, and other environmental factors. It adds a layer of gloss and depth to the paint, making it look more vibrant and professional.
Types of Clear Coat
There are various types of clear coat available, each with its own properties:
- Single-stage clear coat: This type is typically applied in one coat and provides a basic level of protection and gloss. It is a cost-effective option but may not offer the same level of durability as multi-stage clear coats.
- Two-stage clear coat: This type consists of a base coat and a top coat. The base coat provides a smooth, even surface, while the top coat adds gloss and durability. This type offers better protection and a higher gloss finish than single-stage clear coats.
- UV-resistant clear coat: This type is specifically formulated to protect the paint from the damaging effects of ultraviolet (UV) rays from the sun. It helps prevent fading and discoloration, ensuring the paint remains vibrant for longer.
Applying Clear Coat
To achieve a smooth and even finish, it’s essential to apply clear coat correctly:
- Clean the surface: Before applying clear coat, ensure the painted surface is clean and free of dust, debris, and any imperfections. Use a clean, lint-free cloth to wipe down the surface.
- Apply thin coats: Apply multiple thin coats of clear coat rather than one thick coat. This helps prevent runs and sags, ensuring a smooth finish.
- Allow drying time: Allow each coat of clear coat to dry completely before applying the next. The drying time will vary depending on the type of clear coat used and the temperature.
- Sand between coats: Lightly sand between coats with fine-grit sandpaper to smooth out any imperfections and create a smoother finish. This is especially important for multi-stage clear coats.
- Final polish: Once the clear coat has fully cured, you can polish the surface to achieve a high-gloss finish. Use a polishing compound and a soft cloth to remove any remaining imperfections.
