5. Care and Maintenance

To preserve the appearance of your Tamiya Martini Brabham BT44B model, follow these care guidelines:

• Cleaning: Dust the model regularly with a soft, dry brush or a microfiber cloth. Avoid using harsh chemicals or abrasive cleaners, which can damage the paint and plastic.
• Display: Display the model in a cool, dry place away from direct sunlight to prevent fading of paint and decals. Avoid extreme temperature fluctuations.
• Handling: Handle the model carefully, grasping it by the main body or chassis. Avoid putting pressure on delicate parts like wings, mirrors, or antennas.

6. Troubleshooting Tips (Assembly)

Encountering challenges during model assembly is common. Here are some general tips:

• Part Fit Issues: If parts do not fit perfectly, gently sand or trim excess plastic. Test fit parts before applying glue.
• Paint Application: If paint appears uneven or too thick, thin it slightly with appropriate thinner and apply multiple thin coats instead of one thick coat. Ensure each coat is dry before applying the next.
• Decal Silvering: If decals show a silvery film after drying, ensure the surface was glossy before application. Use a decal setting solution to help them conform better and eliminate air bubbles.
• Lost Parts: If a small part is lost, check the floor carefully. For critical parts, contact Tamiya customer support for potential replacements or advice.
• Refer to Instructions: Always re-read the specific steps in the included instruction booklet if you encounter difficulties. Diagrams are crucial for complex assemblies.
