Learn how to customize the HGIBO Shiden with panel lining, decals, and weathering techniques to make your Iron-Blooded Orphans kit stand out.

The HGIBO 025 IO Frame Shiden is a favorite among Iron-Blooded Orphans fans for its rugged, military-inspired design. While the kit looks great out of the box, adding your own touches can elevate it to a display piece that reflects your skills. In this guide, we'll walk through practical steps for detailing and weathering your Shiden, from panel lining to adding decals and simulating battle damage.

Whether you're a beginner looking to try your first customization or a seasoned builder seeking new techniques, this guide covers the essentials. We'll also recommend some products that can make the process easier, like the Aqueous Gundam Color HUG302 Immortal Justice Red for accent details and G-Rework decals for crisp markings.

Prepping Your Shiden for Customization

Before you start adding details, it's crucial to prep the kit. This means removing nub marks carefully with a hobby knife and sanding the surfaces with fine-grit sandpaper. A clean build ensures that paint and panel liner adhere properly. Wash the parts in warm soapy water to remove any mold release agents, then let them dry completely.

If you plan to paint, consider applying a primer. A light gray primer works well for most colors and helps the paint stick. For the Shiden's signature orange and gray scheme, a neutral primer will keep the colors true. Once primed, you can start thinking about your color scheme—whether you want to keep it anime-accurate or go for a custom look.

  • Use a glass file or sanding sponges for smooth surfaces.
  • Wash parts with dish soap and a soft toothbrush to remove oils.

Panel Lining and Detailing

Panel lining is the quickest way to add depth to your Shiden. Use a fine-tipped Gundam marker or Tamiya panel line accent color to fill in the recessed lines. Wipe away excess with a cotton swab dipped in lighter fluid or enamel thinner. For a more subtle look, use gray on light parts and black on dark parts.

To take detailing further, consider adding extra panel lines with a scribing tool or chisel. This is a more advanced technique, but it can break up large flat areas and make the kit look more mechanical. If you're not ready to scribe, you can use thin strips of pla-plate to add raised details, giving the armor a more layered appearance.

  • Practice panel lining on the runner first to get the hang of it.
  • Use a ruler or tape as a guide when scribing new lines.

Adding Decals and Markings

Decals are a great way to add realism and faction markings to your Shiden. The kit comes with foil stickers, but for a more professional look, consider using waterslide decals. G-Rework makes high-quality decals for many kits, and their HGWFM Michaelis Decals can be adapted for the Shiden if you're looking for unique warning signs and emblems. Alternatively, the G-Rework RG Goldymarg Decals offer a variety of generic markings that work well on any mech.

When applying waterslides, use a setting solution like Mark Setter to help them conform to curved surfaces. After they dry, seal them with a clear coat to protect them from scratches and weathering. This is also the time to add any custom paint details, such as painting the inner frame with metallic colors for a more realistic look.

  • Cut decals close to the design to reduce visible film.
  • Apply a gloss coat before decals for better adhesion.

Weathering Techniques for the Shiden

Weathering brings your Shiden to life by telling a story of combat. Start with dry brushing: dip a brush in a lighter color like silver or gunmetal, wipe most of it off on a paper towel, and lightly brush over edges and raised details. This simulates paint chipping and wear. Focus on areas that would see the most action, like the shoulders, knees, and the edges of the shield.

For a more grimy look, use a wash of dark brown or black over the entire kit, then wipe it away with a cloth, leaving residue in crevices. You can also use a sponge to dab on chipping effects—tear a piece of sponge, dip it in paint, and dab it on the armor. Remember to seal everything with a matte topcoat to keep the weathering in place and give the kit a realistic, non-glossy finish.

  • Less is more—start with subtle weathering and build up.
  • Use a reference image of a real military vehicle for inspiration.

Final Touches and Display

Once you're satisfied with the weathering, reassemble your Shiden and pose it. Consider adding a base or diorama to complete the scene. If you want to add a pop of color, you can paint small details like the cameras or sensors with a bright color. The Aqueous Gundam Color HUG302 Immortal Justice Red is perfect for such accents, giving a vibrant red that stands out against the Shiden's earthy tones.

Finally, apply a matte or satin topcoat to unify the finish. This will also protect your work and reduce glare. Display your customized Shiden proudly, and don't be afraid to experiment with different techniques on future builds.

  • Use a photo booth or natural light to capture your work.
  • Keep leftover decals for future projects.

Customizing the HGIBO Shiden is a rewarding project that lets you practice a range of techniques. By following these steps—prepping, panel lining, decaling, and weathering—you can transform a standard kit into a unique masterpiece. For your next build, consider trying the HGAW 109 GX-9900 Gundam X or the 30MM 06 bEXM-15 Portanova [Red] to apply the same skills to different designs.
