Quick Answer

To build the HG Aquarius GG50 SD cleanly, follow the manual order, remove nubs carefully, and test fit joints before applying pressure. These steps keep the build straightforward and reduce the risk of broken parts.

Why the Aquarius GG50 SD Build Differs

The Aquarius GG50 SD is a Standard configuration kit from The Gundam Galaxy, so it follows the typical SD scale approach: smaller parts, simpler articulation, and a quicker build time than a full High Grade. That makes it a good weekend project, but the small pieces demand a bit more care when cutting and sanding.

Because the kit is an SD, the color separation is usually simpler, so panel lining and a topcoat can make a bigger visual difference than they would on a larger kit. Plan for those extra steps if you want the finished model to stand out.

Step-by-Step Assembly Guide

  1. Prep your workspace and tools: Lay out all runners, a hobby knife, nippers, and a cutting mat. Check that you have the manual and confirm all parts are present before starting. Missing parts are easier to spot before you begin than halfway through.
  2. Cut parts from runners carefully: Use a sharp pair of nippers to cut each part away from the runner, leaving a small margin of plastic at the gate. Don't cut flush with the part to avoid stress marks or nicks. Leave a bit of nub – you'll remove it in the next step.
  3. Remove nubs and clean the parts: Trim the remaining nub with a hobby knife, then sand the area with fine grit (400-600) if needed. For a cleaner finish, follow with a higher grit (800-1000) to smooth the surface. Sanding in one direction reduces visible scratches.
  4. Dry-fit parts before applying glue or pressure: Test fit joints and connections without forcing them. If a peg feels too tight, sand it slightly; if it's loose, consider a small drop of glue or paint to thicken it. Dry-fitting prevents cracked plastic and broken pegs.
  5. Assemble in the order shown in the manual: Follow the manual's sequence, usually starting with the head, then torso, arms, and legs. This order helps you access connection points and avoids rework. Skipping ahead can make later steps harder or cause parts to loosen.
  6. Add panel lining and decals: Use a fine-tip panel liner or a wash to define lines, and apply stickers or decals as desired. Let everything dry fully before handling. Panel lining after assembly is easier on SD kits because the parts are small.
  7. Apply a matte topcoat for a clean finish: Spray a thin, even coat of matte topcoat over the completed kit to seal panel lines and protect the plastic. Work in a well-ventilated area and let it cure completely. A topcoat also reduces the shiny plastic look, making the kit feel more premium.
