MR.HOBBY Gundam Metallic Marker Set
The MR.HOBBY Gundam Metallic Marker Set from GSI Creos provides a six-marker assortment with metallic gold, silver, blue, red, and green tones, plus a black brush-type marker for fine hairline work. These markers are ideal for crisp edge highlights, chrome-like panels, and small detailing on Gunpla surfaces. The markers are formulated for smooth application on plastic parts and can deliver high-clarity metallic accents without an airbrush. The included chisel-tip markers broaden application options for broader panel lines.
Designed for modelers who want metallic effects without airbrushing, this set supports precise control along tight panel gaps and recessed lines. The black brush marker is especially useful for hairlines and small detailing, making weathering and weathered chrome effects more accessible. As a ready-to-use option, these markers pair well with standard Gunpla paints and clear coats to achieve durable, high-contrast finishes on display-grade kits.

These paints are pre-thinned for airbrushing and offer high saturation with a mirror-like gloss of up to 85 GU, making mechanical exteriors and sci-fi skins pop on display models.
The kit’s nano-grade pigment dispersion ensures ultra-smooth flow through 0.2mm airbrush setups, helping beginners achieve professional results with minimal dilution. The included thinner and cleaner reduce setup time and cleanup, while the wide color range supports both base colors and fine detailing. This set is well-suited for players who want vibrant, consistent coverage across multiple Gunpla projects without frequent color matching from separate bottles.

Buying Guide
Paint Type and Medium
- Acrylic vs enamel vs marker-based paints each have distinct handling. Acrylics (water-based) dry fast, clean easily with water, and are ideal for plastic models. Enamels cure slowly and require solvents, offering different durability and sheen. Marker-based metallics excel for line work and accents but are not substitutes for full-coverage coats on larger surfaces.
- Marker sets like MR.HOBBY are excellent for detailing and metallic highlights, while airbrush-compatible sets (e.g., Gaahleri Kaleido, Oasser) enable smooth broad coverage and gradient effects.
Finish and Application
- Gloss, satin, and matte finishes affect final appearance and painting technique. Gloss can aid in decaling and topcoat adhesion; matte finishes reduce glare for display models. Consider whether you want a high-gloss mech look or a more muted, battle-damaged finish.
- Airbrush paints require compatible equipment; ensure your tools can handle the included thinning requirements or ready-to-spray formulas.
Color Range and Hue Matching
- Having a broad color range helps reproduce complex Gunpla schemes. Kits that include metallics, primaries, and specialized shades enable precise hue matching for canonical mecha palettes or customized builds.
- Pre-thinned or airbrush-ready lines save time and reduce dilution guesswork, but always test color on a spare piece or an inconspicuous panel.
Tool Compatibility
- Decide between markers for quick detailing and airbrush paints for large areas and smooth gradients. A mixed approach—metallic markers for trims plus acrylics or airbrush paints for base colors—often yields the best results.
- Quality brushes and good cleaning tools extend paint life and reduce color bleed. Tool kits that include finishing accessories support a cohesive workflow from base coat to weathering.
Durability, Drying Time, and Handling
- Water-based acrylics typically dry quickly and cure with minimal odor, making them ideal for home workspaces. Some enamels or solvent-based products may require ventilation and longer curing for handling and topcoating.
- Consider the order of operations: base coat, shading, highlighting, decals, and sealant. A well-timed topcoat protects colors and enhances stability for long-term display.
Safety and Ventilation
- Always use paints in a well-ventilated area and follow manufacturer safety guidelines. Some sets include strong solvents or aerosols; proper storage and handling are essential for hobbyists, especially in smaller spaces.
Budget and Value
- Sets with multiple colors and thinners offer better value for ongoing projects. If you paint frequently, investing in a larger airbrush paint kit plus a reliable marker set can reduce the need to buy many individual bottles.
- Evaluate whether you primarily work on Gundam models or a mix of mecha and civilian kits; choose a kit with compatible color families to minimize duplication and maximize versatility.
