Learn how to apply G-Rework MG Zeta Gundam Ver.Ka waterslide decals for a clean, professional finish. Step-by-step guide with common mistakes to avoid.

Quick answer

Use warm water, a soft brush, and a decal setter to apply G-Rework MG Zeta Gundam Ver.Ka waterslide decals. Work slowly, starting with large flat surfaces, and seal with a topcoat for durability.

Why G-Rework Decals Need Careful Handling

G-Rework waterslide decals are thinner and more detailed than standard stickers, which gives a painted-on look but makes them fragile. The MG Zeta Gundam Ver.Ka has many curved and angled surfaces, so you'll need to plan placement and use setting solutions to avoid silvering or tearing.

Tools You'll Need

Besides the decal sheet, have a shallow dish of lukewarm water, tweezers, a cotton swab or soft brush, a hobby knife, and a decal setting solution (like Mr. Mark Setter). A gloss topcoat before decaling helps the decal adhere and reduces air bubbles.

Step-by-Step Decal Application

Prepare the surface: Make sure the kit is clean and free of dust. Apply a gloss topcoat and let it cure for at least 24 hours. This gives the decal a smooth base and reduces silvering. Skipping the gloss coat is the most common cause of trapped air bubbles.
Cut and soak the decal: Use a sharp hobby knife to cut out one decal close to its edge. Dip it in lukewarm water for 10–15 seconds until the backing paper releases. Do not leave it in water too long or the decal may curl. If the decal doesn't slide off after 20 seconds, the water may be too cold.
Position and slide: Apply a drop of decal setter to the target area. Slide the decal off the paper onto the wet surface using tweezers. Gently nudge it into place with a damp cotton swab. Do not touch the decal with dry fingers. Once the decal touches the plastic, it will start bonding; reposition quickly or use more setter to float it.
Blot and remove excess water: Roll a damp cotton swab from the center outward to push out air bubbles and excess setter. Use a corner of a tissue to wick away liquid. Let it dry completely for at least 30 minutes before handling. Pressing too hard can tear the decal; use gentle, repeated passes instead.
Seal with topcoat: After all decals are dry, apply a final topcoat (gloss, satin, or matte) to protect the decals and blend them into the plastic. This prevents peeling during handling or posing. A matte topcoat reduces decal shine and gives a uniform finish, but test on a spare part first.
