A step-by-step guide to applying G-Rework waterslide decals to the HG GQuuuuuuX GFreD, with checkpoints to avoid silvering and lifting.

Quick answer

Apply G-Rework decals to the HG GQuuuuuuX GFreD by working on a glossy surface, sliding each decal into place with a softener, and sealing it with a topcoat. The process takes patience, but the result is a factory-fresh look.

Why the GFreD’s surface needs extra prep

The HG GQuuuuuuX GFreD has curved armor and subtle panel lines, so decals that sit flat on a glossy surface are less likely to trap air. If you apply them over a matte or textured finish, silvering becomes much harder to avoid.

G-Rework decals are designed specifically for this kit, so the shapes and sizes match the GFreD’s contours. That means you can place them exactly where the instructions or your reference images show, without trimming or guessing.

Tools and workspace

You’ll need a shallow dish of lukewarm water, tweezers, a cotton swab, a soft cloth, decal setting solution, and a gloss topcoat. Keep your hands clean and work in a dust-free area.

A cutting mat and a hobby knife help you separate each decal cleanly. Avoid using paper towels directly on the decal film—they can snag the edges.

Step-by-step decal application

Prepare the surface: Apply a gloss clear coat to the parts you plan to decal and let it cure fully. This gives the decal a smooth base and helps prevent silvering. Check that the surface is tack-free before moving on; a sticky topcoat can wrinkle the decal.
Cut and soak the decal: Cut out the decal with a hobby knife, leaving a small border. Soak it in lukewarm water for 10–20 seconds until it slides easily on its backing paper. Don’t oversoak; if the decal floats off on its own, it may fold or lose adhesive.
Position and slide: Place the decal and backing paper on the model, then gently slide the decal off with a cotton swab. Adjust it into position with the swab or tweezers. Work slowly—once the decal touches the plastic, it grips quickly and can tear if you force it.
Blot and smooth: Use a dry cotton swab to press the decal flat, starting from the center and working outward to push out air and water. If you see trapped air, lift the edge with a knife tip and re-wet slightly before smoothing again.
Apply setting solution: Brush a decal setting solution over the decal to soften it and help it conform to curves and panel lines. Don’t poke or press the decal while it’s soft; let it settle on its own to avoid distortion.
Seal with topcoat: Once the decals are fully dry, apply a clear topcoat (gloss, semi-gloss, or matte) to protect them and unify the finish. Test the topcoat on a spare decal first—some solvents can attack the decal film.
