How to Build and Paint Bandai GQuuuuuuX HG Kit

Quick Answer

Build and paint the Bandai GQuuuuuuX HG kit by carefully removing nub marks, dry-fitting parts before gluing, and using thin paint layers to preserve the sharp detailing of the awakened Endymion Unit.

Step-by-Step Build and Paint Process

1. Step 1: Clean the Runners and Remove Nubs: Use a pair of sharp nippers to cut parts from the runner, leaving a small nub. Trim the nub flush with a hobby knife, then sand with 600-1000 grit sandpaper. Common mistake: cutting too close with the nipper can stress the plastic and leave white marks. Instead, cut a little away and finish with the knife. Test fit each part before gluing or painting to confirm fitment.
2. Step 2: Dry-Fit the Armor and Joints: Assemble the torso, hips, and limbs without glue or paint to check articulation. The head unit can be opened and closed — test this mechanism now. Common mistake: forcing a tight joint can crack the plastic. If a peg feels too tight, sand it lightly with fine grit paper. Mark any areas that need sanding or gap filling before painting.
3. Step 3: Prime the Parts: Disassemble the kit and apply a thin coat of plastic primer (gray or white) to all parts you plan to paint. Hold the can 6-8 inches away and use short bursts. Common mistake: applying too thick a primer layer obscures the sharp detailing. Two thin coats are better than one heavy coat. Let primer cure for at least 24 hours before painting.
4. Step 4: Paint in Thin Layers: Use acrylic or lacquer paints thinned to a milk-like consistency. Apply 2-3 thin coats, allowing each to dry completely. Focus on the awakened Endymion Unit’s distinctive panels. Common mistake: painting over joints without masking them will lock articulation. Mask joint pegs and sockets with tape before spraying. Check paint coverage under bright light after each coat.
5. Step 5: Apply Panel Lining and Decals: Use a fine-tipped panel liner or wash to accent the recessed lines. Wipe away excess with a cotton swab dipped in lighter fluid or enamel thinner. Apply any included stickers or water-slide decals with tweezers. Common mistake: letting panel liner pool on flat surfaces creates blotches. Keep the liner only in the grooves. Seal decals with a gloss coat before weathering or a flat coat for a matte finish.
6. Step 6: Topcoat for Protection: Spray a final clear coat (gloss, satin, or matte) over the entire assembled kit. This protects the paint and decals from chipping. Common mistake: spraying topcoat in humid weather causes frosting. Wait for a dry day with low humidity, or spray indoors with good ventilation. Allow the topcoat to cure for 48 hours before handling or posing the kit.
