4. Assembly Instructions (Setup)
Assembly of the Tamiya Subaru Impreza WRC '99 model kit involves several stages. Refer to the detailed diagrams and step-by-step instructions provided in the physical manual included with your kit for precise guidance.
4.1. Preparation
- Read Instructions: Thoroughly review the entire instruction manual before starting.
- Gather Tools: Prepare necessary tools such as nippers, hobby knife, files, sandpaper, tweezers, and model cement.
- Workspace: Ensure a clean, well-lit, and well-ventilated workspace.
4.2. Part Removal and Cleaning
- Carefully cut parts from the sprues using nippers.
- Trim any excess plastic (flash) or nubs using a hobby knife or file.
- Wash parts with mild soap and water to remove mold release agents, then allow them to dry completely.
4.3. Step-by-Step Assembly
Follow the numbered steps and diagrams in the included paper manual. Each step typically involves:
- Identifying the required parts by their sprue letter and part number.
- Attaching parts using model cement. Apply sparingly to avoid damaging the plastic.
- Allowing sufficient drying time for adhesive before proceeding to the next step.
- Assembling sub-assemblies such as the engine, chassis, interior, and body separately before combining them.

5. Painting and Decal Application
Painting and decal application are crucial for achieving a realistic finish for your model.
5.1. Painting
- Color Codes: The instruction manual provides specific Tamiya paint color codes for each part.
- Preparation: Ensure parts are clean and free of dust before painting. Priming is recommended for better paint adhesion and a uniform finish.
- Application: Apply paint in thin, even coats. Allow each coat to dry thoroughly before applying the next.
- Detail Painting: Use fine brushes for small details and masking tape for sharp lines.
5.2. Decal Application
- Preparation: Apply a gloss clear coat to the areas where decals will be placed to prevent 'silvering'.
- Cutting: Carefully cut out each decal from the sheet.
- Soaking: Dip the decal in lukewarm water for a few seconds until it can slide freely from the backing paper.
- Placement: Slide the decal onto the model surface. Use tweezers and a soft brush to position it correctly.
- Setting Solutions: Use decal setting solutions to help the decal conform to irregular surfaces and eliminate air bubbles.
- Sealing: Once decals are dry, apply a final clear coat (gloss or matte, depending on desired finish) to protect them.

6. Maintenance
Once assembled, your Tamiya model requires minimal maintenance to preserve its appearance.
- Cleaning: Dust your model regularly with a soft, dry brush or a microfiber cloth. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the model in a cool, dry place away from direct sunlight, which can cause paint fading and plastic degradation.
- Handling: Handle the model carefully, avoiding excessive pressure on delicate parts.
7. Troubleshooting
Encountering issues during model assembly is common. Here are some general tips:
- Parts Not Fitting: Ensure you are using the correct parts for the step. Sometimes, a small amount of sanding or filing may be required for a perfect fit.
- Paint Issues: If paint appears uneven or peels, ensure the surface was clean and primed, and that paint was applied in thin coats. Humidity can also affect paint drying.
- Decal Silvering: This occurs when air is trapped under the decal. Ensure a gloss surface before application and use decal setting solutions.
- Missing Parts: Double-check the sprues and packaging. If a part is genuinely missing, contact Tamiya customer support or your retailer.
