Ever looked at your collection of diecast cars and thought, ‘I wish this one had a different paint job’ or ’this one would look awesome with a custom spoiler’? You’re not alone! Diecast customizing is a hugely popular hobby that lets you unleash your creativity and personalize your miniature car collection. It’s a fantastic blend of artistry and precision, and the results are incredibly rewarding.
It’s easier than you think to get started. You don’t need a massive workshop or expensive tools to begin. With a little patience and some basic supplies, you can transform ordinary diecast cars into truly unique works of art. This guide will walk you through the process, from choosing your subject to displaying your finished creations.
Choosing Your Diecast and Project
The first step is choosing the right diecast model. Select a car you enjoy and that has potential for customization. Simple, clean lines often lend themselves well to modifications. Consider the scale too; larger models (1:18 or 1:24) offer more space for detailing, while smaller models (1:64) are perfect for quick projects.

Essential Tools and Supplies
- Hobby knife
- Sandpaper (various grits)
- Acrylic paints
- Paintbrushes
- Clear coat
- Primer
- Glue (appropriate for plastic)
- Small detail brushes
- Masking tape
- Tweezers
You can find many of these supplies at your local hobby store or online. Don’t feel pressured to buy everything at once – start with the basics and expand your collection as you gain experience.

Common Diecast Customization Techniques
There’s a whole world of possibilities when it comes to customizing diecast cars. Here are some popular techniques:
- Repainting: A classic approach that lets you change the entire look of the car.
- Adding decals: Add racing stripes, logos, or other designs to personalize your model.
- Detailing: Enhance the car’s features with small additions, like improved headlights or taillights.
- Custom parts: Swap out parts like wheels, spoilers, or even engines for a completely altered look.
- Scratch building: Create entirely new parts to add to your model, showing off your advanced skills.
Remember, start small. Don’t tackle a complex project right away. Practice on less valuable models first to hone your skills.
