How to build a diecast car

Updated April 17, 2017

Many people enjoy the hobby of building diecast cars. You can build diecast cars within a few hours to a couple of days depending on the difficulty level. Beginners can construct easy diecast cars with few tools; however, more moderate levels require an adequate amount of tools and time.

Place all of the pieces that came in the kit on a table. The body, including the doors, boot and hood, will generally be diecast, whereas the other pieces will be plastic. Put the diecast pieces aside for the moment and keep the plastic parts in front.

Cut out one plastic piece at a time from the plastic grid using a sharp knife. Use the sandpaper to grind down the extra plastic created from the mould of the plastic grid.

Paint each part. Use tweezers to hold the piece, so you can paint the piece without painting your fingers. Allow the pieces to dry for at least 24 hours before continuing to build. If you make any mistakes, use the wet rag to wipe away the paint. Note that many beginner models might not need to have the parts painted due to the easier difficulty level.

Read the instructions that came with the kit. Normally you will have to put the parts together in a specific order. Generally, you build the engine first followed by the interior. Attaching the trim, such as bumpers, mirrors and other components, is usually last. The model kits that are for beginners are usually snap kits, meaning that little to no hobby glue is needed to put on the parts. These pieces easily snap into place. For more difficult models, you must apply glue to each part. Dab a small amount of hobby glue on each part. Firmly press the two parts together for at least 10 seconds and allow the parts to dry for a few hours before continuing.

Assemble the vehicle completely once the glue has dried. Following the instructions, put on the rest of the parts, such as the widows, mirrors and wheels. Display the completed model in a cabinet or on a shelf.


Set aside at least two days when building an intermediate model. The painting and gluing process causes a delay in the build. Use a microfiber cloth to clean any dust particles from the diecast model after the build.
