Ever wished you had a diecast of your favorite driver in a livery that never existed? Or maybe you want to create a fantasy car with your own team colors? Creating your own custom NASCAR diecast is easier than you think! This guide will take you step-by-step through the process, transforming a standard diecast into a one-of-a-kind collectible.
Gathering Your Supplies
Before you start, you’ll need to gather a few essential tools and materials. Don’t worry, you probably already have some of these lying around the house!
- A base diecast car (a readily available model is a great starting point)
- Fine-grit sandpaper (various grades for smoothing and detailing)
- Primer spray paint (choose a color that’ll work well with your final scheme)
- Acrylic paints (your choice of colors for the livery)
- Clear coat spray paint (to protect your amazing paint job)
- Decal paper (for custom numbers, sponsor logos, or any other details)
- Inkjet printer (if you’re making your own decals)
- Small brushes (for precise paint application)
- Masking tape (for sharp lines and clean details)
- Optional: Tweezers, toothpicks, or other small tools for precise decal placement

Preparing the Base Diecast
Start by carefully cleaning your diecast car. Remove any existing decals and gently sand the surface to create a smooth base for the paint to adhere to. Use progressively finer grades of sandpaper to avoid scratching the plastic.

Once you’ve achieved a smooth finish, carefully wipe away any dust particles with a soft cloth. This is crucial for a smooth, even coat of primer.
Priming and Painting
Apply a thin, even coat of primer. Let it dry completely before applying any other paint. Multiple thin coats are better than one thick coat, which can run or drip.
Once the primer is dry, it’s time to unleash your creativity! Carefully apply your chosen paint colors, using masking tape to create clean lines and sharp edges for numbers and stripes. Again, multiple thin coats are recommended.

Allow each coat of paint to dry completely before applying the next. Patience is key here!
Creating and Applying Decals
Designing your decals is where you can really personalize your diecast. You can either create your own designs using graphic design software or find printable templates online. Print your decals onto decal paper, following the manufacturer’s instructions.
Carefully cut out your decals and apply them to the car using a wet application method. This involves applying a thin layer of water to both the decal and the surface of the car, allowing you to reposition the decal if needed before it sets. Gently smooth out any air bubbles.

Sealing the Deal: Clear Coat
After the decals are dry, apply a few thin coats of clear coat spray paint to protect your work. Let it dry completely before handling your masterpiece.
And there you have it! Your very own custom NASCAR diecast, ready to be displayed with pride. Remember to experiment, have fun, and let your creativity shine through. The possibilities are endless!
