What You'll Learn
Choosing the Right Paint and Brushes
Acrylic paints are the go-to choice for painting model tank tracks due to their fast drying time, water solubility, and ease of layering. Unlike enamels, which can take days to cure fully, acrylics allow you to apply multiple coats in a single session, speeding up the weathering and detailing process. For tracks, opt for matte or satin finishes to mimic the worn, metallic surface of real tank treads. Brands like Vallejo, Citadel, or Tamiya offer specialized acrylics designed for scale models, ensuring durability and color accuracy. Always thin your paint with water or a dedicated acrylic thinner to achieve a smooth, even application, especially when working on the intricate details of tracks.
Brush selection is just as critical as paint choice. For the main track surfaces, a flat brush with synthetic bristles (size 2 or 3) provides efficient coverage and control. Synthetic bristles are ideal because they maintain their shape when wet and are less likely to fray, ensuring clean lines. When detailing the individual links or applying rust effects, switch to a smaller round brush (size 0 or 00) for precision. Avoid natural hair brushes, as they can absorb too much moisture and leave streaks. Keep a separate set of brushes for metallic and dark colors to prevent unintended tinting when switching between shades.
Metallic paints require special attention to achieve a realistic finish. Silver or gunmetal shades are commonly used for tracks, but their opacity can be a challenge. Apply metallic paints in thin layers, allowing each coat to dry before adding another. This prevents the paint from pooling in crevices and maintains the crisp definition of the track links. For a more authentic look, mix a small amount of black or dark gray into your metallic paint to tone down the shine and simulate wear. Test your mixture on scrap plastic or cardboard to ensure the color matches your desired effect.
Weathering tracks demands a combination of paints and techniques, but the right tools make all the difference. A stiff-bristled drybrush (size 2 or 4) is essential for applying edge highlights and simulating wear. Load the brush with a light coat of metallic paint, wipe off the excess on a paper towel, and lightly drag it across the raised surfaces of the tracks. This technique instantly ages the tracks by emphasizing their texture. For rust effects, use a fine detail brush to apply orange or brown washes in targeted areas, blending them with a clean, damp brush for a natural transition.
Finally, consider the scale of your model when choosing paint and brushes. Smaller scales (1/72 or 1/144) require finer brushes and thinner paint applications to avoid obscuring details, while larger scales (1/35 or 1/24) allow for more dramatic weathering effects. Regardless of scale, consistency is key—use the same brand and type of paint throughout the project to ensure uniform drying times and finishes. Invest in high-quality brushes and clean them thoroughly after each use to prolong their lifespan. With the right tools and techniques, painting tank tracks becomes a rewarding process that elevates the realism of your model.

Preparing the Tank Surface for Painting
The surface of your model tank is the canvas upon which the tracks will be painted, and its preparation is critical to achieving a realistic and durable finish. Before you even think about applying paint, ensure the surface is free from mold release agents, grease, and dust. These contaminants can prevent paint from adhering properly, leading to chipping or peeling over time. A simple yet effective method is to wash the tank with warm, soapy water, followed by a rinse with isopropyl alcohol to remove any residual oils. Allow the surface to dry completely before proceeding.
Once cleaned, inspect the tank for imperfections such as mold lines, seams, or ejector pin marks. These flaws can detract from the final appearance, especially on the tracks, where detail is paramount. Use a fine-grit sandpaper (800–1200 grit) to gently smooth out these areas, taking care not to remove too much material. For deeper imperfections, consider filling them with a two-part epoxy putty or a specialized modeling filler, sanding again once it has cured. The goal is to create a seamless surface that enhances the track details rather than competing with them.
Priming is a step often overlooked but is essential for achieving a professional finish. A primer acts as a bridge between the plastic or resin surface and the paint, improving adhesion and providing a uniform base for color. Choose a primer specifically formulated for plastic models, such as an acrylic or lacquer-based option. Apply thin, even coats using an airbrush or spray can, holding the nozzle 6–8 inches away from the surface. Allow each coat to dry before adding another, ensuring full coverage without obscuring the track details. A well-primed surface will not only enhance paint adhesion but also make it easier to achieve smooth, consistent color application.
Finally, consider the texture of the surface when preparing for track painting. Tracks often have a worn, weathered appearance, and the base surface can influence how this effect is achieved. If you plan to simulate rust, mud, or wear, lightly sanding the primer in select areas can create subtle variations in texture, adding depth to your weathering effects. Alternatively, applying a thin layer of textured paint or using a weathering powder directly on the primed surface can enhance realism. The key is to think ahead about the final look you want to achieve and tailor your surface preparation accordingly.

Techniques for Smooth Track Application
Achieving a smooth, seamless track application on model tanks requires precision and the right techniques. One critical step is preparing the tracks before painting. Ensure the tracks are free from mold release agents or oils by cleaning them with isopropyl alcohol and a soft brush. This removes surface contaminants that can hinder paint adhesion, creating a smoother finish. Skip this step, and you risk uneven paint application or peeling over time.
Consider the paint application method as a key factor in achieving smoothness. Airbrushing is often preferred over brush painting for tracks due to its ability to lay down thin, even coats. Use a paint thinner-to-acrylic ratio of 1:1 to ensure the paint flows smoothly without pooling. Hold the airbrush 2-3 inches from the surface, moving in steady, overlapping passes. This technique minimizes brush strokes and ensures consistent coverage, especially in the intricate details of tank tracks.
A less-discussed but effective technique is the use of a track assembly jig. By mounting the tracks on a jig before painting, you maintain proper tension and alignment, preventing sagging or misalignment. This is particularly useful for individual track links, which can be tedious to handle. Once painted, allow the tracks to dry completely before removing them from the jig to avoid smudging or distortion.
Finally, post-painting techniques can enhance smoothness. Apply a gloss coat followed by a matte or satin varnish to seal the paint and reduce the appearance of imperfections. Lightly sanding the tracks with 2000-grit wet sandpaper between coats can further smooth the surface, but exercise caution to avoid damaging fine details. This layered approach ensures durability and a professional finish, making your model tank’s tracks stand out.

Weathering and Detailing Painted Tracks
Tracks on model tanks, once painted, often lack the realism of their full-size counterparts. Weathering and detailing techniques bridge this gap, transforming pristine tracks into battle-worn components that tell a story. The key lies in understanding the interplay of wear, dirt, and environmental exposure.
Start by identifying high-wear areas: the top surface where the track contacts the wheels, the edges where debris accumulates, and the inner surfaces where grease and grime build up. These areas will receive the most intense weathering effects.
Layering is crucial. Begin with a base coat of your chosen track color, allowing it to dry completely. Then, using a lighter shade of the same color or a metallic paint, dry brush the raised surfaces to highlight details and simulate wear. This technique involves loading a small amount of paint onto a stiff brush, removing most of it on a cloth, and then lightly brushing the raised areas. The result is a subtle, natural-looking wear pattern.
For a more pronounced effect, consider using a wash. Mix a dark wash (a thin, translucent paint) with water to achieve a consistency similar to milk. Apply the wash generously over the tracks, allowing it to pool in recesses and crevices. Once dry, gently wipe away excess wash from raised surfaces with a damp brush or cloth. This technique accentuates details and creates the illusion of dirt and grime accumulation.
Rust and chipping add further realism. Using a rust-colored paint, apply small dots or streaks to areas prone to rust, such as where metal meets metal or where damage might occur. For chipping, use a fine brush and a lighter color than the base track color. Gently dab the brush onto the surface, creating small, random chips. This technique mimics the wear and tear of combat and exposure to the elements.
Remember, less is often more. Subtle weathering and detailing can be more effective than overdoing it. Observe reference photos of real tanks to understand the natural wear patterns and apply these observations to your model. With patience and practice, you can transform your model tank's tracks from mere plastic into a convincing representation of a battle-hardened machine.

Sealing and Protecting the Finished Tracks
Once your model tank's tracks are meticulously painted, sealing them is crucial to preserve their appearance and durability. Exposure to handling, dust, and environmental factors can degrade the paint over time. A protective coat acts as a barrier, ensuring your hard work remains intact.
Choosing the Right Sealant
Not all sealants are created equal. Matte varnishes are ideal for tracks, as they maintain the metallic or weathered look without adding unwanted gloss. Acrylic-based sprays are user-friendly and dry quickly, but apply thin coats to avoid obscuring fine details. For a more durable finish, consider enamel-based sealants, though they require longer drying times and proper ventilation. Test your chosen product on a scrap piece first to ensure compatibility with your paint.
Application Techniques
Hold the spray can 8–10 inches away from the model, moving in smooth, even strokes. Multiple light coats are better than one heavy application, which can cause pooling or frosting. For brush-on sealants, use a high-quality synthetic brush and apply in thin layers, following the direction of the track links. Allow each coat to dry completely—typically 20–30 minutes for acrylics, 1–2 hours for enamels—before adding another.
Cautions and Troubleshooting
Avoid sealing in humid conditions, as moisture can cause clouding. If you notice imperfections after sealing, gently sand the area with 2000-grit paper and reapply the sealant. Be mindful of over-handling the tracks during the sealing process, as fresh sealant can smudge easily. For added protection, consider applying a second layer of sealant after 24 hours, focusing on high-wear areas like the underside of the tracks.
Long-Term Maintenance
Even with sealing, periodic maintenance can extend the life of your tracks. Store your model in a dust-free environment and handle it by the hull, not the tracks. If the sealant begins to wear, reapply a light coat annually. For heavily used display models, consider using a modular track system that allows for easy replacement of damaged sections without repainting the entire tank.
By investing time in sealing and protecting your tracks, you ensure your model tank remains a stunning centerpiece for years to come.
