Premium airbrush models from established brands like Hobbynox, Vallejo, Createx, Badger, and Iwata offer durable construction and precision engineering with consistent CFM airflow ratings.

Best Nozzle Sizes for Different RC Painting Techniques

4 main nozzle sizes serve different RC painting applications: 0.2mm, 0.3mm, 0.5mm, and 0.8mm. The medium 0.5mm option provides excellent balance between coverage and precision for most paint job applications on model car bodies.

Nozzle Size Applications:

• 0.2mm: Ultra-fine lines, detail accents, weathering effects
• 0.3mm: Fine lines, decal work, small graphics
• 0.5mm: General body coverage, medium gradients, most effects
• 0.8mm: Base coats, large coverage areas, quick color blocking

Paint viscosity must be properly adjusted when using finer nozzles to flow smoothly. Water-based airbrush paint typically requires less thinning than solvent-based options, making it easy to use across different nozzle sizes on polycarbonate substrates.

Compressor Requirements and Air Pressure Settings

RC airbrushes operate effectively at 15-45 PSI (1-3 bar) pressure with oil-free compressors providing steady 2-4 CFM airflow. The air pressure you use affects paint atomization and spray pattern on lexan surfaces.

Compressor Features for RC Painting:

• Pressure range: 15-45 PSI (1-3 bar) for optimal paint flow
• Tank option: Models with air tanks provide steadier pressure
• Oil-free design: Prevents contamination of paint and air lines
• Noise level: Quiet operation for indoor use

Compressors with tanks offer more consistent air delivery, while tankless models may produce slight pressure variations. Both types get the job done effectively for RC car body painting applications on polycarbonate substrates.

RC Airbrush Paint FAQs

Does airbrushing need primer?

Lexan-compatible airbrush paints require no primer when applied to clean polycarbonate surfaces. These paints are formulated for direct adhesion to polycarbonate. However, applying primer improves adhesion on hard plastic or when switching paint types.

How many coats of paint when airbrushing?

Apply 2 to 4 thin coats of airbrush paint for full coverage on RC car bodies. Thinner coats prevent runs, improve drying, and allow better layering for gradients or effects when proper PSI pressure is maintained. Let each coat dry before applying the next.

What to clean an RC body with before paint?

Clean an RC body with warm water and mild detergent to remove mold release and oils before applying any airbrush paint. Dry thoroughly to ensure proper adhesion of airbrush or spray paint to the polycarbonate lexan surface.

Can you use regular spray paint on RC car bodies?

Do not use regular spray paint on RC car bodies. Standard paints crack and peel on flexible polycarbonate lexan when the substrate flexes during use. Use lexan-compatible paints like water-based airbrush or PS-series spray paints for proper adhesion and durability.
