Maintenance
Once assembled and painted, your model tank requires minimal maintenance. To preserve its appearance:
- Cleaning: Dust the model regularly with a soft, dry brush or a can of compressed air. Avoid using water or chemical cleaners, as these can damage paint or decals.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent fading and warping. A display case can protect it from dust and accidental damage.
- Handling: Handle the model carefully, especially delicate parts like antennas, machine guns, and photo-etched details. Avoid dropping or applying excessive pressure.
Troubleshooting
Encountering issues during model assembly is common. Here are some tips:
- Parts Not Fitting: Ensure you are using the correct parts as indicated in the instruction diagrams. Lightly sand or trim excess plastic (flash) from parts if they are too tight. If parts are too loose, a small amount of filler or thicker glue can help.
- Decal Issues: If decals do not adhere well, ensure the surface is glossy and clean. Use decal setting solutions to help them conform to irregular surfaces and adhere better.
- Paint Problems: If paint appears uneven or peels, ensure the surface was clean and properly primed (if necessary) before painting. Apply paint in thin layers rather than one thick coat.
- Missing or Damaged Parts: Carefully check all sprues and packaging. If a part is genuinely missing or damaged, contact the manufacturer or retailer with your proof of purchase and the specific part number.
