How to Paint Your Gundam Model: Airbrushing vs Hand Painting

Painting your Gundam model is one of the most rewarding steps in the hobby. It transforms a plain plastic kit into a personalized masterpiece. But before you start, you need to choose your weapon: airbrush or hand brush. Both have their strengths and weaknesses, and the right choice depends on your goals, budget, and patience.

In this guide, we'll break down the differences between airbrushing and hand painting, explore the best paints for each method, and offer practical tips to help you get the best results—whether you're a beginner or a seasoned builder.

Airbrushing: Pros and Cons

Airbrushing is the go-to method for many Gundam builders because it delivers a smooth, even coat that mimics the factory finish of a professionally painted kit. With an airbrush, you can achieve subtle gradients, shading, and color modulation that are nearly impossible with a brush. It's also faster for covering large surfaces, especially on 1/100 or larger kits.

However, airbrushing requires a significant upfront investment. You'll need an air compressor, an airbrush, a spray booth, and safety gear like a respirator. There's also a learning curve—mastering paint consistency, air pressure, and nozzle control takes practice. Plus, cleaning the airbrush between colors can be tedious.

• Smooth, even finish with no brush strokes
• Ideal for gradients and shading effects
• Faster for large parts, but setup and cleanup take time
• Higher initial cost and requires ventilation

Hand Painting: Pros and Cons

Hand painting is the most accessible way to paint your Gundam. All you need is a set of quality brushes, some paints, and a palette. It's perfect for small parts, details, and touch-ups. Many builders prefer hand painting for panel lines, eyes, and other fine features because it gives you precise control.

The downsides are that hand painting can leave visible brush strokes if you're not careful, and achieving an even coat on large flat surfaces is challenging. It's also slower, especially if you need multiple thin coats to avoid streaks. But with the right technique—thinning your paints and using multiple thin layers—you can get impressive results.

• Low cost and easy to start
• Great for details and small parts
• Requires patience and practice to avoid brush strokes
• Not ideal for large surfaces or smooth gradients

Choosing the Right Paint for Your Gundam

The type of paint you use matters just as much as your application method. For hand painting, acrylic paints are the most beginner-friendly because they clean up with water and have low odor. Brands like Tamiya and Vallejo offer a wide range of colors. For airbrushing, you can use acrylics, lacquers, or enamels. Lacquers dry fast and are durable, but they require stronger solvents and better ventilation.

If you're painting a kit like the 1/35 Barbatos Gundam Bust Model Kit, you'll want a paint that adheres well to the plastic and can handle the intricate details. For larger kits like the Daban 8812A MB Style MG 1/100 Astray Red Frame Kai, consider using a primer first to ensure the paint sticks and lasts.

• Acrylics: water-based, easy to clean, great for beginners
• Lacquers: durable, fast-drying, but need good ventilation
• Enamels: oil-based, smooth finish, but longer drying time
• Always use a primer for better adhesion and color accuracy

Step-by-Step: How to Paint Your Gundam with an Airbrush

1. Prepare your workspace: ensure good ventilation, lay down a cutting mat, and set up your spray booth. 2. Disassemble your kit and wash the parts in warm soapy water to remove mold release agents. 3. Prime the parts with a fine primer, either in a matching color or gray. 4. Thin your paint to the consistency of milk and test spray on a scrap piece. 5. Apply light, even coats from about 15-20 cm away, allowing each coat to dry before the next. 6. After painting, seal with a clear coat to protect the finish.

For a kit like the GG MGSD Wing Gundam Zero EW Rebellion Ver. (Third Party), which has many small parts, you might want to paint in sub-assemblies to reach every nook and cranny. Patience is key—rushing will lead to drips and uneven coverage.

• Always test spray on a spare part before painting the actual kit
• Use multiple thin coats rather than one thick coat
• Clean your airbrush thoroughly after each session

Step-by-Step: How to Hand Paint Your Gundam

1. Prepare your paints by thinning them with water or a suitable thinner—aim for a consistency that flows smoothly but doesn't pool. 2. Use a good quality brush with a fine tip for details and a flat brush for larger areas. 3. Apply thin coats, letting each dry completely before adding another. 4. For large flat surfaces, use a technique called 'wet blending' to smooth out brush strokes. 5. After the final coat, consider applying a topcoat to even out the finish and protect the paint.

Hand painting is perfect for adding fine details to kits like the Holographic Water Decal for MGEX Unicorn Gundam 1/100—you can paint the decal itself or the surrounding areas to create a custom look. Just remember to use a steady hand and take your time.

• Invest in a good set of brushes—cheap brushes lose bristles and ruin finishes
• Thin your paints more than you think necessary
• Use a palette to mix and control paint consistency

Whether you choose airbrushing or hand painting, the key is to practice and enjoy the process. Both methods have their place in a modeler's toolbox.
