Diecast models are cherished collectibles, often representing significant investment in time and money. To maintain their value and aesthetic appeal, it’s crucial to keep them in pristine condition. This blog post will guide you on preserving your diecast models and keeping them rust-proof.
Understanding the Enemy: Rust
Rust is the result of a chemical reaction between iron, oxygen, and moisture. While diecast models are typically made from a zinc-aluminum alloy (Zamak), small parts may contain iron that can rust over time. Rust not only mars the appearance of your models but can also cause structural damage.
Prevention is Better Than Cure
1. Control the Environment: Store your models in a dry, temperature-controlled environment. High humidity and temperature fluctuations can accelerate rusting.
2. Display Cases: Consider using display cases to protect your models from dust and moisture. Ensure the cases are made from materials that do not release damaging vapors.
3. Handling: Always handle your models with clean, dry hands. Oils and sweat from your skin can contribute to rusting.
Rust-Proofing Your Models
1. Protective Coatings: Applying a thin layer of protective wax or oil can create a barrier against moisture. Ensure the product is safe for use on diecast models to avoid damaging the paintwork.
2. Silica Gel Packs: These can be placed in your display case or storage box to absorb excess moisture.
3. Regular Cleaning: Dust your models regularly to remove any moisture-trapping particles. Use a soft brush or microfiber cloth to avoid scratching the model.
Dealing with Rust
If you notice rust on your model, it’s important to address it promptly to prevent further damage.
1. Light Rust: For light surface rust, try gently rubbing it off with a pencil eraser or a piece of aluminum foil dipped in water.
2. Heavy Rust: For more severe rust, professional restoration may be necessary. It’s crucial to weigh the cost of restoration against the model’s value.
Conclusion
Preserving your diecast models and keeping them rust-free is an essential part of the hobby. With proper care and attention, you can ensure your collection remains in top condition for years to come. Happy collecting!
