Maintenance
Once assembled, your model requires minimal maintenance:
- Cleaning: Dust your model regularly with a soft brush or a can of compressed air. Avoid using harsh chemicals or abrasive materials.
- Display: Display your model in a stable, dust-free environment away from direct sunlight and extreme temperature fluctuations to prevent fading or warping.
- Handling: Handle the model carefully, grasping it by sturdy sections to avoid damaging delicate parts.
Troubleshooting
Common issues encountered during model building and their solutions:
- Parts not fitting: Ensure all sprue gates are cleanly removed and check for any flash. Dry fit parts before gluing. Sometimes slight sanding or trimming may be necessary.
- Glue marks: Use glue sparingly. If excess glue appears, try to remove it carefully with a cotton swab dipped in a small amount of appropriate solvent (test on scrap plastic first) or gently scrape once dry.
- Paint issues: Ensure surfaces are clean and dry before painting. Apply thin coats of paint to avoid brush strokes or thick layers. Allow adequate drying time between coats.
- Decal silvering: Apply decals to a glossy surface. Use decal setting solutions to help decals conform to irregular surfaces and eliminate air bubbles.
