Metallic Inner Frames With Alclad Paints

A metallic inner frame can transform a Gundam kit from a simple assembly into a convincing mechanical structure. Alclad paints are especially useful for this job because their lacquer formula produces thin, smooth layers that preserve molded detail while creating convincing aluminum, steel, and chrome effects.

The finish depends less on the metallic color itself than on preparation. Clean plastic, controlled airbrushing, and a suitable base coat determine whether the result looks like machined metal or grainy silver paint. Work patiently, and even an entry-level kit can gain a far more substantial presence. For a beginner-friendly build reference, see this Strike Gundam review.

Choose Paint And Prepare Parts

Alclad II includes several useful shades for inner frames, including Steel, Dark Aluminum, Magnesium, Stainless Steel, and Chrome. Darker colors usually suit joints, pistons, and structural blocks, while brighter aluminum works well on exposed armor mechanisms. Combining two or three related shades creates depth without requiring elaborate weathering.

Remove mold-release residue, fingerprints, and sanding dust before painting. Wash the parts in warm water with a small amount of dish soap, rinse thoroughly, and allow them to dry completely. Handle cleaned pieces with gloves or tweezers so skin oils do not interfere with adhesion.

Build A Surface That Reflects Light

For most Alclad metallics, a smooth gloss black base is the safest starting point. Apply a compatible black lacquer primer or gloss black base in light, even passes. The surface should appear uniformly glossy, with no dry patches, orange peel, or visible sanding marks. Metallic paint will emphasize every flaw underneath it.

Allow the base to cure according to the product instructions before applying the metal color. A rushed base can soften under the lacquer layer or become marked by masking tape. If the inner frame includes flexible polycap material, test a hidden area first; paint may crack when those parts are repeatedly moved.

Spray The Metallic Layers

Use an airbrush with good ventilation and appropriate respiratory protection, since Alclad lacquer produces strong fumes. A moderate pressure setting and a small nozzle are generally effective, but the ideal combination depends on the airbrush and paint mixture. Begin with a mist coat, wait briefly, then build coverage through several thin passes.

Keep the airbrush moving and maintain a consistent distance from the part. Heavy coats can pool around bolt details and soften edges, while spraying too far away may create a dusty texture. Alclad is usually ready for handling relatively quickly, but give the parts additional curing time before masking, especially in humid conditions.

Match The Metallic Effect To The Part

Different metallic shades suggest different materials. A uniform silver frame often looks flat, while carefully placed variations make the assembly feel engineered. Use brighter finishes on sliding rods and raised surfaces, then reserve darker tones for recessed armor, joint housings, and areas that would collect grime.

Chrome deserves special care because it reflects the quality of the base more strongly than ordinary metallic shades. Use it sparingly on small parts rather than covering an entire inner frame. A semigloss or matte clear coat will reduce its mirror effect, so leave selected chrome details unsealed if the model will be handled gently.

Mask, Seal, And Assemble

Once the metallic layer has cured, mask sections with low-tack tape or carefully cut masking film. Press the tape down only along the edge that needs protection, and remove it by pulling it back over itself at a shallow angle. If possible, mask broad, sturdy surfaces rather than delicate pistons or sharp corners.

Clear coating is optional. A light gloss coat can protect frequently handled parts, while a satin finish gives most inner frames a realistic manufactured appearance. Matte coats can make metal look dusty and dull, so apply them selectively. Avoid assembling tight joints immediately after painting; even a dry surface may still be vulnerable to friction.

Recommendations For A Clean Inner Frame

A reliable workflow is easier to repeat when each stage has a specific purpose. Keep spare runners or unused frame parts nearby for testing paint, pressure, masking tape, and clear coats before committing to visible sections.

• Prime and paint parts in subassemblies that remain easy to hold and inspect.
• Use different metallic shades for neighboring mechanical components.
• Test lacquer compatibility on leftover plastic from the same kit.
• Leave friction areas unpainted or remove paint from pegs and sockets.
• Photograph each stage so color placement can be repeated on matching limbs.

Planning the order of painting also prevents unnecessary handling. Paint deep frame sections first, then add pistons, armor brackets, and small highlights. If a part will be hidden after assembly, focus effort on edges and openings that remain visible through the armor.

Correct Common Problems

A grainy surface usually indicates paint drying before it reaches the part. Move the airbrush closer, reduce airflow slightly, or apply a thinner wet pass while keeping the nozzle moving. Runs and pooling mean the coat is too heavy; allow the piece to cure, smooth the defect carefully, and respray rather than trying to wipe it immediately.

If the metallic finish looks weak, inspect the base coat before adding more color. Uneven gloss black, excessive distance, or a dull primer can reduce reflectivity. Fingerprints after painting are another common issue, so use clean gloves and support parts with clips or alligator holders.
