Choosing the Right Materials: The Key to a Flawless Finish

Selecting the right materials is crucial for achieving a durable and professional-looking paint job. Here’s a breakdown of the essential supplies:

* **RC Car Body:** Polycarbonate (Lexan) bodies are the most common and are designed to flex without cracking. Ensure it is clean before starting.
* **Paints:** Polycarbonate-specific paints are essential. These paints are flexible and won’t crack or peel when the body flexes. Brands like Tamiya, Pactra (now discontinued but still available), and Duratrax are popular choices. Avoid using standard automotive paints, as they are not designed for flexible surfaces.
* **Masking Tape:** High-quality masking tape, such as Tamiya masking tape, is essential for creating clean lines and preventing paint bleed. Different widths are useful for various applications.
* **Liquid Mask:** Liquid mask is a great alternative to masking tape for complex shapes and designs. It’s applied as a liquid and then peeled off after painting.
* **Cutting Tools:** A sharp hobby knife or a specialized Lexan scissors are needed for trimming the body and cutting out decals.
* **Cleaning Supplies:** Dish soap and warm water are sufficient for cleaning the body before painting. Isopropyl alcohol can be used to remove stubborn residue.
* **Primer:** While not always necessary, a polycarbonate-specific primer can improve paint adhesion, especially on older bodies.
* **Clear Coat:** A polycarbonate-specific clear coat adds an extra layer of protection and enhances the gloss and depth of the paint job.
* **Sandpaper:** Fine-grit sandpaper (400-600 grit) can be used to lightly scuff the surface for better paint adhesion. Use with caution.
* **Airbrush or Spray Cans:** An airbrush provides the most control and allows for intricate designs, but spray cans are a more affordable and convenient option for beginners.
* **Respirator:** Always wear a respirator when painting to protect yourself from harmful fumes.
* **Gloves:** Wear gloves to prevent fingerprints and oil from contaminating the surface.

Step-by-Step Guide: Painting Your RC Car Body

Follow these steps to achieve a professional-looking paint job on your RC car body:

1. Preparation: Cleaning and Masking

* **Clean the Body:** Wash the RC car body thoroughly with dish soap and warm water to remove any dirt, grease, or mold release agents. Rinse well and allow it to dry completely. Use a microfiber cloth to avoid scratches.
* **Mask the Windows:** Use masking tape to carefully cover the windows and any other areas you don’t want to paint. Overlap the tape slightly to prevent paint bleed. For curved areas, use smaller pieces of tape to follow the contours.
* **Apply Liquid Mask (Optional):** For complex designs or areas that are difficult to mask with tape, apply liquid mask. Follow the manufacturer’s instructions for application and drying time.

2. Painting: Applying the Base Coat

* **Ventilation:** Ensure you are working in a well-ventilated area. Use a spray booth if possible.
* **Shake the Paint:** Shake the paint can thoroughly for at least two minutes to ensure the pigments are evenly distributed.
* **Test Spray:** Before painting the body, test the paint on a piece of cardboard or scrap plastic to check the color and spray pattern.
* **Apply Thin Coats:** Apply the paint in thin, even coats, holding the can about 10-12 inches from the body. Overlapping each pass slightly. Avoid applying too much paint in one coat, as this can lead to runs and drips. Remember, multiple thin coats are better than one thick coat.
* **Drying Time:** Allow each coat to dry completely before applying the next. Refer to the paint manufacturer’s instructions for drying times. Typically, 15-30 minutes between coats is sufficient.
* **Multiple Colors:** If you’re using multiple colors, start with the darkest color first and work your way to the lightest. Mask off the areas you want to protect before applying each color.

3. Detailing: Adding Stripes, Graphics, and Decals

* **Masking:** Use masking tape or liquid mask to create stripes, graphics, or other custom designs. Plan your design carefully and use a sharp hobby knife to cut the masking material.
* **Airbrushing:** An airbrush allows for more intricate designs and gradients. Practice your technique on scrap material before painting the body.
* **Decals:** Apply decals after the paint has dried completely. Use a decal setting solution to help the decals adhere to the surface and prevent air bubbles.

4. Clear Coat: Protecting Your Paint Job

* **Apply Clear Coat:** Apply a polycarbonate-specific clear coat to protect the paint job and enhance its gloss and depth. Use the same technique as with the base coat, applying thin, even coats.
* **Drying Time:** Allow the clear coat to dry completely before handling the body. Refer to the manufacturer’s instructions for drying times. Usually 24 hours.

5. Finishing Touches: Removing the Masking and Trimming

* **Remove Masking:** Carefully remove the masking tape or liquid mask after the clear coat has dried completely. Use a hobby knife to score the edges of the masking material before peeling it off to prevent the paint from chipping.
* **Trim the Body:** Use Lexan scissors to trim any excess material from the body. Follow the manufacturer’s instructions for trimming.
* **Mount the Body:** Mount the body onto your RC car chassis. Make sure the body posts are properly aligned.

Advanced Techniques: Taking Your Painting to the Next Level

Once you’ve mastered the basics, you can explore these advanced techniques to create truly stunning paint jobs:

* **Candy Colors:** Candy colors are translucent paints that are applied over a metallic base coat to create a deep, shimmering effect.
* **Color Shifting Paints:** Color shifting paints change color depending on the viewing angle, creating a mesmerizing effect.
* **Hydro Dipping:** Hydro dipping is a process of transferring a printed design onto a three-dimensional object using water. It’s a great way to create complex patterns and textures.
* **Sanding and Polishing:** Sanding and polishing the clear coat can remove imperfections and create a super-smooth, glossy finish.

Troubleshooting: Common Painting Problems and Solutions

Even with careful preparation, painting problems can still arise. Here are some common issues and how to fix them:

* **Paint Runs:** Paint runs are caused by applying too much paint in one coat. To fix a run, let the paint dry completely, then sand it down with fine-grit sandpaper and repaint the area.
* **Orange Peel:** Orange peel is a textured surface that resembles the skin of an orange. It’s caused by the paint drying too quickly or being applied in too thick of a coat. To fix orange peel, sand the surface smooth with fine-grit sandpaper and repaint it.
* **Paint Cracking:** Paint cracking is caused by using the wrong type of paint or applying it to a dirty or unprepared surface. To fix paint cracking, remove the cracked paint, prepare the surface properly, and repaint it with the correct type of paint.
* **Paint Peeling:** Paint peeling is usually caused by poor adhesion. Ensure the surface is properly cleaned and primed before painting.
* **Fish Eyes:** “Fish eyes” are small, circular craters in the paint. They are usually caused by contamination on the surface. Clean the surface thoroughly and repaint the area.
