When building and painting plastic models, choosing the right paint finish is crucial to achieving the desired look and feel for your model. Whether you're creating a sleek aircraft, a rugged military vehicle, or a shiny race car, the finish you choose can dramatically impact the final appearance of your model. But with so many options—gloss, matte, and satin—how do you know which one is right for your project? This guide will help you understand the differences between these paint finishes and when to use each one for the best results.
What Are Paint Finishes?
A paint finish refers to the final appearance of a painted surface in terms of its sheen or glossiness. Different finishes affect how light interacts with the surface of your model, making it look shiny, dull, or somewhere in between. The most common finishes in model painting are gloss, matte, and satin.
Gloss: A shiny, reflective finish that makes the surface look polished.
Matte: A flat, non-reflective finish that reduces light reflection and gives a dull appearance.
Satin: A middle-ground finish with a slight sheen, offering a balance between gloss and matte.
Each of these finishes serves a different purpose, and the choice of finish can change the way your model looks and feels.
Gloss Finish: When to Use It
A gloss finish has a shiny, mirror-like surface that reflects light, giving your model a polished and clean look. Gloss finishes are typically used on models where the real-life counterpart would have a shiny or polished appearance, such as modern cars, aircraft, and high-end machinery. This finish is also useful for applying decals, as the smooth surface helps the decals adhere without any air bubbles or silvering best paint for plastic models.
Advantages of Gloss Finish
Shiny and polished appearance: Makes the model look brand new and clean.
Decal-friendly: The smooth surface is perfect for applying decals without trapping air.
Easy to clean: Glossy models are easier to wipe clean and maintain.
When to Use Gloss Paint on Models
Aircraft models: Especially modern jets or commercial airliners with polished surfaces.
Cars and vehicles: For shiny finishes, such as sports cars or race cars.
Science fiction or futuristic models: Robots, spaceships, and other sci-fi subjects often look great with a sleek, glossy finish.

Matte Finish: When to Use It
A matte finish gives a model a flat, non-reflective look that absorbs light instead of reflecting it. Matte finishes are ideal for military vehicles, aircraft, and other models where a worn, rugged, or tactical appearance is desired. Matte finishes can make the model look more realistic in certain contexts, especially for subjects that aren’t shiny in real life, such as tanks, artillery, and historical aircraft.
Advantages of Matte Finish
Realistic appearance: Especially for military and weathered models.
Less light reflection: The flat surface reduces reflections, adding to a model’s realism.
Easier weathering: Weathering techniques like dry brushing and washes often look better on a matte surface.
When to Use Matte Paint on Models
Military models: Tanks, artillery, and armored vehicles.
Historical aircraft: Especially WWII-era planes with camouflage patterns.
Dioramas and scenery: Terrain elements, buildings, and landscapes.

Satin Finish: When to Use It
A satin finish falls between gloss and matte, offering a slight sheen without being overly reflective. It’s a versatile option that gives your model a smooth look with a subtle shine, ideal for subjects that need a bit of both finishes. Satin finishes are often used on figures, mecha models, or vehicles that benefit from a semi-polished look without being too glossy.
Advantages of Satin Finish
Balanced appearance: Not too shiny, not too dull—a good compromise between gloss and matte.
Subtle sheen: Adds depth to the model without overwhelming the details.
Great for figures and mecha: Brings out the details while keeping the model looking realistic.
When to Use Satin Paint on Models
Mecha or Gundam models: The slight sheen adds to the mechanical look without being overly reflective.
Military vehicles: Satin finishes can be used when you want a slightly worn yet clean appearance.
Sci-fi figures: Characters or robots can benefit from a satin finish for a futuristic look.

How to Apply Paint Finishes Correctly
The way you apply paint and the finish can significantly affect the final appearance of your model. Here are some tips for achieving the best results with different paint finishes:
Surface Preparation
Regardless of the finish you choose, surface preparation is key. Make sure your model is clean, free of dust, and primed before applying the final paint. Use a primer suited for the type of paint (acrylic, enamel, etc.) you are using.
For gloss finishes, the smoother the surface, the better. Sand the surface lightly with fine-grit sandpaper for a smooth finish.
For matte finishes, a more textured surface can help enhance the flat appearance.
For satin finishes, the surface should be smooth but not overly polished.
Thin Coats for Best Results
Whether you're using gloss, matte, or satin paint, always apply multiple thin coats instead of one thick coat. This ensures an even finish and reduces the risk of paint runs or bubbles.
Gloss finishes: Build up thin layers to achieve a smooth, shiny surface.
Matte finishes: Thin layers help prevent an overly chalky or uneven look.
Satin finishes: A few light coats will bring out the slight sheen without making the model too shiny.
Use a Clear Coat for Protection
To protect your model and give it the final finish, apply a clear coat that matches your chosen finish.
Gloss clear coats: Used to seal gloss finishes and protect decals.
Matte clear coats: Dullcote or matte varnish will maintain the flat appearance.
Satin clear coats: Offers a balanced protection without changing the sheen too much.
When to Mix Finishes
Sometimes, using a combination of finishes on different parts of the same model can create a more dynamic and realistic effect.
Gloss on cockpit canopies or windshields: For vehicles or aircraft, using gloss on glass parts adds realism.
Matte on the body, gloss on details: For military models, use matte on the main body but gloss on metallic parts like weapons or machinery.
Satin on uniforms, matte on gear: For figures, using satin on clothing or armor while keeping gear or accessories matte adds visual contrast.
Common Mistakes to Avoid
Overuse of Gloss
While gloss finishes look great on certain models, using too much can make your model look unrealistic. High-gloss finishes are best reserved for clean, shiny subjects like cars and sci-fi ships.
Forgetting to Protect Decals
Always apply a gloss finish before applying decals, as this will prevent silvering and ensure the decals adhere properly. After the decals are dry, you can apply a matte or satin topcoat if desired.
Not Considering the Real-Life Counterpart
Always consider what the real-life counterpart of your model would look like. Military tanks don’t have shiny, reflective surfaces, and race cars don’t have flat, non-reflective paint.
Conclusion
Choosing the right paint finish—gloss, matte, or satin—can dramatically enhance the appearance of your plastic models. Gloss finishes provide a sleek, polished look, matte finishes are ideal for rugged and realistic models, and satin finishes offer a balanced middle ground. By understanding when and how to use each type of finish, you can make your models look as realistic and eye-catching as possible.
