4. Assembly (Setup)
The Bandai Gundam Wing Sandrock Custom EW MG 1/100 kit features snap-fit construction, eliminating the need for adhesive. The plastic is pre-colored, minimizing the need for painting to achieve the intended appearance.
4.1 Tools Required
- Hobby Nipper: Essential for cleanly removing parts from the plastic runners.
- Hobby Knife (Optional): Useful for cleaning nubs and mold lines for a smoother finish.
- Tweezers (Optional): Recommended for applying water transfer decals.
4.2 Assembly Steps
- Part Removal: Carefully cut each part from its runner using a hobby nipper. Cut slightly away from the part first, then make a second, closer cut to minimize stress marks.
- Nub Cleaning: Use a hobby knife or fine-grit sandpaper to carefully remove any remaining plastic nubs from the cut points. This ensures parts fit together correctly and improves appearance.
- Follow Instructions: Refer to the included pictorial instruction manual for the specific assembly sequence. Each section (head, torso, arms, legs, weapons) is typically built independently before being combined.
- Snap-Fit: Gently press parts together until they snap into place. Do not force parts, as this can cause breakage.
- Decal Application: After assembly, apply the water transfer decals according to the decal placement guide in the instruction manual. Cut out the desired decal, dip it in water for a few seconds, then slide it onto the model. Use tweezers to position it correctly and a cotton swab to absorb excess water.

5. Posing and Display (Operating)
Once assembled, your Gundam model is highly articulated, allowing for a wide range of dynamic poses. Handle the model gently to avoid stressing joints or detaching parts.
5.1 Articulation
The Master Grade series is known for its advanced internal frame and extensive articulation. Joints in the neck, shoulders, elbows, wrists, waist, hips, knees, and ankles allow for expressive posing. Move joints slowly and deliberately to understand their range of motion.
5.2 Accessories
The Sandrock Custom EW comes with several iconic accessories:
- Heat Shotels (x2): These large, curved blades can be held in the hands or stored on the back. They feature alternate red transparent blades for a heated effect.
- Diffusing Cloak: A fabric-like cloak that can be draped over the model, replicating its iconic appearance.
- Beam Machine Gun: A ranged weapon that can be held in either hand.
- Shield: Attaches to the arm for defensive poses.
Experiment with different combinations of accessories and poses to recreate scenes or create your own dynamic displays.

6. Care and Maintenance
Proper care will preserve the appearance and longevity of your model kit.
- Dusting: Regularly dust your model using a soft brush or compressed air to prevent dust buildup in crevices.
- Cleaning: For stubborn dirt, gently wipe with a slightly damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent plastic degradation or discoloration.
- Handling: Always handle the model by its main body parts, avoiding delicate antennas or small accessories.
7. Troubleshooting
7.1 Loose Joints
Over time, some joints may become loose due to repeated posing. To address this:
- Clear Coat: Apply a thin layer of clear acrylic topcoat (matte or gloss) to the ball or peg of the loose joint. Allow it to dry completely before reassembling. This adds a thin layer of material, increasing friction.
- Tissue Paper: For a temporary fix, a tiny piece of tissue paper can be placed inside the joint socket before inserting the peg.
7.2 Broken Parts
If a part breaks during assembly or handling, small amounts of plastic cement can be used for repair. For significant damage or missing parts, contact Bandai customer support for potential replacement options.
