Step-by-step build guide for the Premium Bandai HGUC Hi-Zack Custom A.O.Z RE-BOOT Ver. 1/144 kit, covering prep, assembly, and finishing.
Quick Answer
For a clean, durable build of the Premium Bandai HGUC Hi-Zack Custom A.O.Z RE-BOOT Ver., focus on careful nub removal, dry-fitting joints, and applying panel line accents after assembly.
Why This Kit Deserves a Careful Build
The RMS-106CS Hi-Zack Custom from the A.O.Z RE-BOOT line features a distinctive silhouette with unique backpack and shield details. As a Premium Bandai exclusive, the kit uses specialized runners and decals that reward patient assembly.
Because it's an HG kit, the engineering is straightforward, but the small parts and tight joints mean you should work slowly. Rushing can lead to stress marks or loose connections that are hard to fix later.
Build Steps
- Prep Your Workspace and Tools: Gather a nipper, hobby knife, sanding sticks or glass file, and a cutting mat. Organize runners by letter to avoid mixing parts. Ensure good lighting and ventilation. A clean workspace prevents losing small parts and reduces mistakes.
- Cut and Clean Each Part: Cut parts from runners with a sharp nipper, leaving a small nub. Trim the nub with a hobby knife, then sand with fine-grit sticks to smooth the surface. Avoid over-sanding that can flatten details. Check for stress marks on dark plastic; sand gently to remove them without altering the shape.
- Dry-Fit the Inner Frame and Joints: Before applying any adhesive or paint, dry-fit the major assemblies—arms, legs, and torso—to check fit and movement. Sand any tight pegs lightly to avoid cracking plastic when you press them together. If a joint feels too tight, sand the peg, not the socket, to maintain a secure fit.
- Apply Panel Line Accents: Use a fine-tip panel liner or a wash to accent the recessed lines. Apply sparingly, let it dry, then clean up with a cotton swab and enamel thinner. Avoid getting liner on the clear parts or the chest camera. Test the liner on a runner scrap first to ensure it doesn't craze the plastic.
- Assemble the Head and Torso: Follow the manual for the head and torso, being careful with the small camera and antenna parts. Insert the neck joint securely, then attach the torso to the waist. Ensure the chest vents are aligned. The antenna is fragile; handle it by the base and avoid twisting it during installation.
- Build and Attach the Arms and Legs: Assemble each arm and leg, paying attention to the orientation of the elbow and knee joints. Attach them to the torso, and test the range of motion. If a joint is too loose, apply a thin layer of hobby glue and let it dry to increase friction. Check that the shoulder and hip connections are fully seated before moving on.
- Finish with Decals and Topcoat: Apply the included stickers or water-slide decals (if provided) using tweezers. Seal everything with a matte or gloss topcoat to protect the finish and decals. Allow full drying time before posing. Topcoat in a well-ventilated area and apply thin, even coats to avoid frosting.
