Try the straw method: blow paint around with a straw until it's too thin, then drip more in a new place
To create a marble effect on a Lexan RC body, you can try the straw method. This involves using a straw to blow paint across the surface to create a unique and abstract design. Here's a step-by-step guide:
Start by choosing your paint colours. You can use liquid watercolours or, if you don't have those, try watered-down food colouring or tempera paint. Prepare your paint by adding a few drops of paint to each colour to thin it out slightly.
Next, decide on the base colour for your RC body. Spray a light coat of this colour onto the Lexan body. While the paint is still wet, you can start the straw technique. Place a small amount of your next chosen colour onto a paintbrush and drip a few dots onto the wet base coat.
Now, take your straw and position it about one inch above the paint dots. Blow through the straw with a quick burst of breath. This will cause the paint dots to explode and create a splatter effect. You can adjust the distance and force of your blowing to achieve different splatter sizes and patterns.
Repeat this process, adding more paint dots and blowing with the straw until you're happy with the marble effect. Remember to clean your paintbrush between colours to avoid mixing unintended colours on your palette.
As a tip, you can cut your straw in half to make your blowing action more effective and precise. Additionally, if you're concerned about inhaling paint accidentally, you can poke a small hole halfway up the straw with a pin.
Finally, once you've achieved your desired marble effect, allow the paint to dry completely before handling or adding any additional coats or effects.
The straw method is a fun and creative way to achieve a unique marble design on your Lexan RC body. With some practice and experimentation, you can create a wide range of abstract patterns and effects.

Use a sea sponge: dab wet paint onto the body, then back with another colour
To achieve a marble effect on a Lexan RC body, one method is to use a sea sponge to dab wet paint onto the body and then back it with another colour. This technique can create an interesting and unique pattern that resembles marble. Here's a step-by-step guide on how to do it:
Prepare the Lexan RC Body
Before you start painting, it's important to prepare the Lexan RC body surface. Clean the body with dish soap and a sponge to remove any dirt, grease, or mould release chemicals. Rinse it well with plain water and let it dry completely.
Choose Your Paint Colours
Select two or more paint colours that you want to use for the marble effect. You can experiment with different colours to see which combinations you prefer. Candy red and silver are a popular choice, but you can also try using metallic purple or blue, backed with white or black to adjust the brightness or darkness.
Start Painting with the Sea Sponge
Pour or spray a small amount of your first chosen paint colour onto a plate or palette. Dip the sea sponge into the paint and then gently dab it onto the Lexan RC body. Apply the paint in irregular patterns, creating a unique marble-like texture. You can overlap colours and create veins that resemble marble. Work on one section at a time to control the drying process.
Add the Second Colour
While the first colour is still wet, quickly dab on the second colour with the sea sponge. You can create interesting effects by partially mixing the colours together or creating distinct veins and swirls. Remember to work in small sections to control the drying time.
Back with Another Colour (Optional)
If desired, you can add a backing colour to adjust the overall tone of the marble effect. For example, you can spray a light coat of silver or black at the back of the Lexan body to enhance the colours and create a more dramatic effect.
Experiment and Practice
It's important to experiment and practice on spare pieces of Lexan before attempting the final piece. This will help you get a feel for how the colours combine and blend, and you can refine your technique to achieve the desired marble effect. Remember to let the paint dry completely before assessing the results.

Drip paint directly onto the inside of the lexan and blow it across with a straw
To achieve a marble effect on a Lexan RC body, one method is to drip paint directly onto the inside of the Lexan and blow it across with a straw. This technique creates a unique and organic pattern that resembles marble veins. Here's a step-by-step guide:
Prepare the Lexan Surface:
Before starting the painting process, it's crucial to prepare the Lexan body properly. This includes removing any protective coatings, thoroughly cleaning the surface with dish soap and water to remove grease or oil, and drying it completely with a soft, lint-free cloth. Ensure that you are working in a well-ventilated area and wearing the appropriate protective gear, such as gloves and a respirator.
Choose the Right Paint:
Select paints specifically designed for Lexan or polycarbonate surfaces, such as hobby-grade paints like Tamiya and DuraTrax. These paints have solvents that bond well with Lexan, ensuring durability and a long-lasting finish. Avoid using regular spray paints, as they tend to flake off due to their hardness.
Drip and Blow Technique:
With your chosen paint colors, drip small amounts of paint directly onto the inside of the Lexan body. You can experiment with different colors and their placement to create the desired marble effect. Use a straw to gently blow on the wet paint, directing the airflow to guide the paint and create organic veins and patterns. Vary the intensity and direction of your breath to achieve different effects.
Experiment with Layers:
You can create depth and complexity in your marble effect by layering different paint colors. Allow each layer to dry partially before adding the next, and use the drip and blow technique for each layer. This approach will give the illusion of three-dimensional veins and swirls, enhancing the marble-like appearance.
Practice and Creativity:
As with any artistic endeavor, practice makes perfect. Experiment with different paint colors, drip sizes, and blowing techniques on a practice piece of Lexan before attempting it on your RC body. Explore various marble styles and color combinations to find the effect that suits your taste and the overall design of your RC vehicle.
Remember, this technique may require some trial and error, but with patience and creativity, you can achieve a stunning marble effect on your Lexan RC body that will surely turn heads!

Spray a thick layer of paint, then dab it with scrunched-up plastic wrap
To create a marble effect on a Lexan RC body, one of the methods you can use involves spraying a thick layer of paint and then dabbing it with scrunched-up plastic wrap. This technique is a simple and effective way to achieve a unique and organic marble pattern. Here's a step-by-step guide to help you through the process:
Prepare the Work Area:
Before you begin, make sure you have a well-ventilated work area. Cover your work surface with a drop cloth or newspaper to protect it from paint splatters. Gather all the materials you need, including your chosen spray paint colour, a can of water, plastic wrap, gloves, and a face mask if desired.
Spray a Thick Layer of Paint:
Start by spraying a thick layer of paint onto the Lexan RC body. You can use a single colour or experiment with different colours for a more vibrant effect. Apply the paint evenly and thoroughly to ensure complete coverage. It is advisable to practice on a separate piece of Lexan or a test surface to get a feel for the technique before applying it to your final piece.
Dab with Scrunched-up Plastic Wrap:
While the paint is still wet, take a piece of plastic wrap and scrunch it up into a ball. The size of the plastic wrap should be large enough to cover the area you want to create the marble effect on. Begin dabbing the wet paint gently with the scrunched-up plastic wrap. Apply light pressure and move the plastic wrap around the painted surface to create a unique pattern. You can vary the pressure and the angle at which you dab to create different effects.
Allow the Paint to Dry:
Once you're happy with the marble pattern you've created, set the piece aside and allow the paint to dry completely. This step is crucial, as it will ensure that your design stays intact and doesn't smudge. The drying time may vary depending on the type of paint you use and the thickness of the layer.
Add Additional Layers (Optional):
After the first layer of paint has dried, you can decide if you want to add more depth and complexity to your marble effect. Spray additional layers of paint in different colours or shades to enhance the marbling. Remember to allow each layer to dry before applying the next one.
Finish and Protect Your Work:
Once you've achieved the desired marble effect and the paint has dried, you may want to consider sealing your work with a clear coat or varnish to protect the paint job and ensure its longevity. Choose a sealant that is suitable for the surface and follow the manufacturer's instructions for application.
Creating a marble effect on a Lexan RC body using spray paint and plastic wrap is a creative way to add a unique touch to your project. Remember to take your time, experiment with different colours and techniques, and always work in a well-ventilated area.

Hydro dipping: dip the inside of the body in water and use hydro dipping film
Hydro dipping is an effective way to paint a marble effect on the inside of an RC Lexan body. The process involves dipping the inside of the body in water and using hydro dipping film to create the desired effect.
Firstly, you will need to source a high-quality hydrographic film and chemical activator from a reputable supplier. Ensure the film is of good quality to avoid issues with the film not liquefying properly and creating an unwanted plastic bag-like effect. Japanese-made films are recommended by some hobbyists.
Next, prepare the RC body by cleaning, trimming, and final fitting. It is important that the body is ready for painting. Leave the protective film on the outside of the body, so the dip only affects the inside.
Then, fill a large container with water. A 45-gallon plastic storage bin is a good option to consider. Spray your chosen paint into the water and swirl it to create the desired marble effect. It is important to work quickly as the texture of the paint can deteriorate fast.
Once you are happy with the swirled paint, dip the inside of the RC body into the water. Ensure the body is fully submerged to avoid air bubbles, which can cause issues with the film adhering to the polycarbonate.
Finally, remove the RC body from the water and allow it to dry. You can then duct tape the inside of the body to protect the paint job.
