If you are a diecast car collector, you may have heard the term "paint rash" before. It's one of the biggest issues collectors face with their diecast model cars over time. Paint rash occurs when the paint starts to bubble, crack, or peel off due to various factors, such as exposure to sunlight, humidity, or chemicals. In this blog post, we'll discuss what paint rash is on diecast model cars and how to prevent it.
What Is Paint Rash?
Paint rash is a term used to describe the paint deterioration process that occurs on diecast model cars. It happens due to exposure to UV rays, humidity, chemicals, and other environmental factors. It mostly affects the topcoat of the paint, causing small bubbles or cracks that can later develop into larger areas of peeling or flaking. Paint rash can significantly reduce the value and appearance of your diecast model car and can be tricky to fix.
What Causes Paint Rash?
Several factors contribute to the occurrence of paint rash. Continuous exposure to direct sunlight and UV rays can cause the paint to crack or bubble. High humidity can also cause paint rash, producing moisture under the paint surface, leading to its detachment or peeling. Finally, exposure to chemicals like cleaning products and car waxes can adversely affect the paint's quality and lead to paint rash.
How To Prevent Paint Rash
Taking preventive measures can help prolong the life of your diecast model cars and prevent paint rash from happening in the first place. Here are some tips to keep in mind:
- Store your diecast model cars in a cool and dry place, away from direct sunlight, humidity, and chemical exposure.
- Avoid using harmful cleaning products or housekeeping chemicals to clean your diecast model cars.
- Apply a protective coating or wax on the cars to prevent the paint's direct exposure to UV rays and moisture.
- Always handle your diecast model cars carefully, avoiding any rough use that can cause scratches or damage to the paint.
Whether you're caring for Honda toy cars or a rare collector's item, preventing paint rash is essential to preserve the value of your items.
How To Fix Paint Rash
If you already have paint rash on your diecast model cars, you can try fixing it with simple solutions. Clean the car with mild soap and water, then gently sand the affected area with fine-grit sandpaper. Next, apply a putty-like filler on the gaps or peeling areas and let it dry. Once it dries, sand it again and apply a thin primer layer. Finally, apply a clear coat over the primer with color-matching paint.
Care for Your Model Car's Appearance and Value
Paint rash is a common problem faced by diecast car collectors, but there are ways to prevent it and fix it if it does occur. Understanding what paint rash is and how to deal with it is essential for anyone collecting diecast model cars. If your cars develop paint rash, following the above steps can help restore their appearance and value.
