Gundam Holographic Decals: What They Are and How to Use Them

If you've been building Gunpla for a while, you've probably seen builds with a mesmerizing, rainbow-like sheen that shifts as you move them. That effect comes from holographic decals, also known as holo decals. These specialty water slides have become increasingly popular among modelers who want to add a unique, eye-catching twist to their kits. In this guide, we'll explain what holographic decals are, how they differ from standard decals, and how to use them effectively on your Gundam models.

Whether you're a beginner or a seasoned builder, understanding holo decals can open up new creative possibilities. From subtle accents to full-body coverage, these decals can transform a plain kit into a showpiece. Let's dive into the world of holographic decals and see what they can do for your Gunpla.

What Are Holographic Decals?

Holographic decals are a type of water slide decal that features a microscopically etched surface that diffracts light, creating a rainbow or prismatic effect. Unlike standard decals that have a flat, opaque finish, holo decals have a translucent, iridescent quality that changes color depending on the viewing angle and lighting conditions. This makes them perfect for adding a dynamic, futuristic vibe to your Gundam models.

These decals are often used to replicate the 'psycho-frame' glow seen in many Gundam series, or to give a kit a custom, otherworldly look. They can be applied over painted surfaces, clear parts, or even bare plastic, and they work best when placed on a dark or glossy base to maximize the holographic effect.

• Holographic decals are water slides, so they require the same application process as standard decals.
• They are translucent, so the underlying color will show through and affect the final appearance.
• For the best effect, apply them over a smooth, glossy surface.

Holographic vs. Standard Decals: Key Differences

The main difference between holographic and standard decals is the visual finish. Standard water slides are typically opaque and have a matte or gloss finish, while holo decals are translucent with an iridescent sheen. This means holo decals don't completely cover the surface; instead, they add a layer of color and light that blends with the underlying paint.

Another difference is the application process. While both use water to transfer the design, holo decals can be slightly more delicate due to their thinness. They also require a bit more care when cutting and positioning, as the holographic effect can make it harder to see the edges. However, with practice, they become just as easy to use as regular decals.

• Holo decals are more transparent, so plan your base color carefully.
• They can be used alongside standard decals for a mixed effect.
• Always use a soft decal solution to help them conform to curved surfaces.

Types of Holographic Decals for Gundam

There are several types of holographic decals available for Gundam kits, ranging from generic effects sheets to model-specific sets. Generic holographic decals often feature warning signs, caution stripes, or abstract patterns that can be used on any kit. Model-specific sets, like the Holographic Water Decal for MGEX Unicorn Gundam 1/100, are designed to fit particular kits and include markings that match the original design.

You can also find holographic decals that are designed for specific parts, such as the Evo RG Gundam 00 Raiser XN (00RXN) Water Decal, which adds holographic accents to the 00 Raiser. These sets are perfect for builders who want to enhance a particular kit without having to design their own decals.

• Generic holo decals are versatile and can be used on any kit.
• Model-specific sets ensure a perfect fit and authentic look.
• Look for decals from reputable brands like Evo for quality and durability.

How to Apply Holographic Decals: Step-by-Step Guide

Applying holographic decals is similar to applying standard water slides, but there are a few extra tips to ensure a flawless finish. Start by cutting out the decal you want to use, leaving a small margin around the edges. Soak it in warm water for about 10-15 seconds, or until the decal loosens from the backing paper. Slide it onto the desired location, positioning it carefully with a cotton swab or tweezers.

Once in place, gently press out any air bubbles and excess water. Use a soft cloth or cotton swab to apply gentle pressure from the center outward. For curved surfaces, apply a decal softener like Mark Softer to help the decal conform. After the decal has dried, you can apply a topcoat to seal it and protect it from scratches.

• Use warm water to activate the adhesive, but not too hot to avoid damaging the decal.
• Apply a decal softener for curved parts like shoulders or shields.
• Seal with a clear topcoat after the decal is completely dry.

Tips for Using Holographic Decals Effectively

To get the most out of your holographic decals, consider the placement and the base color. Dark colors like black, navy, or deep red make the holographic effect pop, while light colors may wash it out. Glossy surfaces also enhance the iridescence, so consider applying a gloss coat before adding the decals.

Another tip is to use holographic decals sparingly. A little goes a long way, and too many holo decals can make your kit look busy. Use them as accents on key parts like the shoulders, chest, or weapons to draw attention to specific areas. You can also combine them with standard decals for a balanced look.

• Test on a spare piece first to see how the effect looks on your paint.
• Use holo decals on dark or metallic colors for maximum impact.
• Combine with standard decals for a professional, layered look.

Holographic decals are a fantastic way to add a unique, eye-catching element to your Gundam models. Whether you're enhancing a favorite kit or creating a custom masterpiece, these decals offer a level of visual interest that standard decals can't match.
