Adding Details to Your HG Gundam

Adding details to your HG Gundam helps it look more realistic and customized. This involves careful panel lining, applying stickers and decals, and basic painting techniques.
Panel Lining for Realism
Panel lining is used to emphasize the lines and details on the Gundam model. To do this, you can use a fine-tipped Gundam marker or a mechanical pencil. Carefully trace the lines on the model.
Wipe away excess ink with a cotton swab or a clean cloth. This creates a sharp and clean outline. Panel lining brings out the details and gives the model a more defined and mechanical look.
Color options for panel lining can vary. Common choices are black, gray, and brown. Each color can add a different effect to your model.
Applying Stickers and Decals
HG Gundam kits often include stickers and decals to add specific designs or insignias. First, carefully cut the stickers from the sheet with a pair of hobby scissors. Tweezers can help place the stickers accurately.
Use a soft tool or a cotton swab to press down the stickers firmly. Decals may require water application. Dip the decal in water for a few seconds, then slide it onto the desired spot.
Use a soft cloth to pat the decal dry and remove excess water. This process adds more authenticity and detail to the model, making it stand out.
Basic Painting Techniques

Although HG Gundam models come molded in different colors, painting can enhance their look. Begin with basic colors like red, blue, white, and gray. Acrylic paints are recommended for beginners as they are easy to clean and quick to dry.
Use small brushes for detailed areas and larger brushes for bigger parts. Apply thin layers of paint and let each layer dry before applying the next.
Consider using masking tape to cover areas you don't want to paint. Weathering techniques can also be used to give the model a more battle-worn look. This adds depth and realism to the Gundam model.
Advanced Gunpla Techniques
Enhancing your High Grade (HG) Gundam model involves customizing, applying weathering effects, and creating dynamic displays. These advanced techniques can significantly improve the visual appeal and realism of your builds.
Customizing Your HG Model
Customizing goes beyond following the instructions in the kit. Builders can change colors, add new parts, or modify existing elements. Painting is a major component. Use airbrushes for smooth finishes, and hand-paint details for precision. Applying panel lining with fine markers or washes enhances the model’s details.
Builders often use third-party parts or materials like plastic sheets to create custom armor or weapons. Another advanced technique is sanding and puttying, which helps to smooth seams and fill gaps, making the model look more polished.
Decals and stickers can also be customized. Waterslide decals tend to look more realistic than standard stickers. Whether you're adding special insignias or custom markings, decals can make your model stand out. Experimentation and practice are key to mastering these customizing techniques.
Weathering for Aged Effects
Weathering techniques add a sense of realism by simulating wear and tear. Common methods include dry brushing where paint is lightly applied to raised surfaces to highlight edges and create a worn look. Builders often use washes to fill crevices with darker shades, simulating dirt and shadow effects.
Chipping effects mimic the appearance of damaged paint. This can be achieved by applying silver paint with a sponge or using a fine brush. Additionally, pastels and pigments can be used to create rust and dust effects. This enhances the aged appearance, making it look like it's seen many battles.
Remember to protect your work with a clear topcoat once the weathering is complete. This helps to seal the effects and keep the details intact.
Creating Dioramas and Displays
Dioramas and displays set your model in a dynamic scene, enhancing its visual story. Base building involves creating a foundation using materials like foam, plaster, or clay. This base can represent environments like battlefields, space stations, or natural landscapes.
Details are crucial. Adding elements such as rocks, vegetation, or debris can create a more immersive setting. Using items like mini LED lights can bring another level of realism, especially in spaceships and night scenes.
Posing your model correctly within the diorama is vital. Ensure that the pose or action matches the scene’s narrative. Perspective and scale should be considered to maintain realism. Accessories like stands or layers can add depth and complexity to the display, making it more engaging for viewers.
Maintaining and Displaying Your Gundam
Maintaining your High Grade (HG) Gundam models ensures they stay in great shape, while proper display choices highlight their best features.
Cleaning and Maintenance
Regular cleaning is key to keeping your Gundam models looking good. Dust can collect on them, making them appear dull. Use a soft, anti-static brush to gently remove dust from small parts and crevices. A can of compressed air can help blow away dust from hard-to-reach areas.
For tougher dirt, dip a cotton swab in mild soapy water and gently clean the affected area. Avoid using harsh chemicals, as they can damage the plastic. After wet cleaning, make sure to dry the model thoroughly to prevent water spots.
Inspect your model periodically for loose parts or joints. If you find any, a small drop of plastic cement can help secure them. Handle your model with care during cleaning to avoid breaking any delicate parts.
Display Options and Stands
Displaying your Gundam models properly can enhance their appearance and protect them from damage. Display stands are a popular choice as they allow you to pose your Gundam in dynamic positions. Some stands are adjustable, which means you can change poses without buying new stands.
Display cases offer another layer of protection by keeping dust away. These cases come in various sizes and styles, so you can choose one that suits your collection. Using a clear acrylic case lets you view your models from all angles without having to open it frequently.
For a more elegant display, use shelves with built-in lighting. LED lights can highlight the fine details of your models. When setting up shelves, make sure they are sturdy and placed away from direct sunlight to prevent color fading.
By following these guidelines, your High Grade Gundam models will remain in pristine condition and look impressive on display.
