What You'll Learn
Sanding and priming
Sanding
Lightly sand the plastic surface to dull its shine and create a scuffed texture. This step is especially important if your plastic surface is very smooth. Fine-grit sandpaper is a suitable choice for this task. However, if your plastic is already scratched and beaten up, you can skip sanding. The goal is to create a slightly roughened surface that will allow the primer and paint to adhere better, resulting in a more authentic metal-like finish.
Priming
Primer selection plays a significant role in achieving the desired metallic effect. You can choose between black, gray, or clear plastic primer. Black primer can create a deeper metallic look, making it ideal for props and cosplay projects. It also helps to enhance the texture and makes thin spots in the paint more visible. On the other hand, gray primer provides a great matte finish and adheres well to plastic. You can find gray automobile primer at most home improvement stores. Clear primer is another option if you want to maintain the original color of the plastic while adding a metallic sheen.
After selecting the appropriate primer, it's important to apply two thorough coats of primer to the plastic surface. Allow sufficient drying time between coats, typically about an hour. The primer should be completely dry before proceeding to the next step. Once the primer is dry, you can lightly sand it to achieve a smoother finish. This step is crucial if you want to achieve a seamless metal-like appearance.
In conclusion, sanding and priming are essential steps in the process of making plastic look like shiny metal. By following these steps, you will create a textured and primed surface that will enhance the overall authenticity and shine of the metallic finish.

Using silver spray paint
Painting plastic to look like shiny metal can be done in a few simple steps. The first step is to prepare the plastic surface. If the plastic is very smooth, roughen it up with fine-grit sandpaper. If the plastic is already a little scratched, you can skip this step. Next, wash the plastic with mild soap and water, and dry it with a paper towel or let it air dry.
The next step is to prime the plastic. Spread out newspaper on your work area, as well as on the walls and floor, as spray paint particles can spread. Put on safety glasses and work gloves, and spray the plastic with two coats of plastic primer. Allow 15 minutes between coats, and at least one hour for the second coat to dry completely. You can use either black or clear primer; black may help create a deeper metallic look.
Now, you can apply the silver spray paint. Spray one thorough coat of silver paint onto the plastic surface, wait an hour, and then apply a second lighter coat to fill in any thin spots. Allow the paint to dry for up to 24 hours before use. You can create a rough, beat-up metal look by rubbing the silver paint onto the black primer with a clean cloth and building up layers of silver paint.
To add a hint of shine to your project, you can dry brush some metallic silver paint over the primer. This will give it a shiny, new metal look. If you want your project to look like old, aged metal, you can rub black furniture wax onto the silver paint.

Applying a black wash
Painting plastic to look like metal is a simple process, but achieving a shiny, metallic finish can be challenging. One way to enhance the metallic effect is by applying a black wash.
A black wash is a simple and quick technique that can be used to create a variety of finishes, from vintage metal to black iron. It involves applying a thin layer of black paint or stain to the surface and then immediately wiping off the excess with a damp cloth or towel. This allows the black to settle into crevices and creates a natural-looking finish. The excess can be removed by spraying the surface with water and then smoothing the paint with a soft, clean, dry brush. This process can be repeated until the desired effect is achieved.
For a simple black wash, you can use black paint straight out of the jar, or you can thin it with a little water to increase its translucency. A small amount of soapy water can also be added to the mixture to help break up the surface tension and create a smoother finish. It is important to wear gloves when applying the wash, as it can be a messy process.
There are also dedicated products available, such as Pro Acryl black wash or Citidel Nullin Oil, which can be applied in thin layers and repeated until the desired effect is achieved.
When applying a black wash over metallic paint to create a black iron effect, it is important to let each layer of paint dry completely before applying the next. This technique can be used to create an old or dirty look, but it may require some experimentation to get the desired result.

Using graphite
Painting plastic to look like shiny metal can be achieved by using graphite powder. This method can be done by first applying a layer of black paint to the plastic surface and then rubbing graphite powder on top to achieve the desired metallic sheen.
Alternatively, a more thorough process can be followed, which will result in a more durable and authentic finish. Firstly, it is important to prepare the plastic surface by washing it with mild soap and water. Once the plastic is dry, use fine-grit sandpaper to roughen the surface, which will help the paint adhere better. If the plastic is already scratched, this step can be omitted.
Next, apply a coat of black or grey primer to the plastic. This will provide a base for the metallic paint and help to achieve the desired colour. It is important to allow the primer to dry completely before moving on to the next step.
Once the primer is dry, a thin coat of chalkboard paint can be applied using a foam brush. This paint should be immediately wiped off with a rag, leaving a thin layer that will create a matte finish.
The final step is to add a hint of shine to achieve the metallic look. This can be done by lightly dry-brushing silver paint onto the surface with a chip brush. Only a small amount of paint is needed, and the excess should be wiped off onto a paper towel before applying.
This process can be repeated as necessary until the desired level of shine is achieved. It is important to allow the paint to dry completely between coats, and to work in a well-ventilated area to avoid inhaling spray paint particles.

Adding shine with chalkboard paint
Painting plastic to look like shiny metal can be achieved in a few simple steps. Firstly, it is important to prepare the plastic surface by washing it with mild soap and water and allowing it to dry completely. If the plastic is very smooth, roughen the surface with fine-grit sandpaper to give the paint something to adhere to. Next, apply a primer. A grey automobile primer is a good choice as it adheres well to plastic and provides a suitable base colour for the desired metallic finish. Allow the primer to dry completely before proceeding to the next step.
Now, it's time to add the chalkboard paint. Using a foam brush, apply a thin coat of chalkboard paint to the primed surface. Immediately after application, wipe away any excess paint with a rag. This will ensure that the chalkboard paint does not overwhelm the underlying primer layer and helps create a more textured, metallic appearance.
To add shine, there are a few different approaches you can take. One option is to use silver paint. Dry brush a thin layer of silver paint onto the chalkboard paint to give it a subtle sheen. Alternatively, you can use a wax with a glossy finish. Apply a thin coat of wax and buff it with a soft cloth to bring out the shine. Repeat this process after each layer of wax, building up the desired level of shine and protection.
If you want an even glossier finish, consider using a product like Minwax Polycrylic in Semi-Gloss or Gloss. Apply this over the chalk paint instead of wax for a high-shine finish. Remember to always work in a well-ventilated area when using spray paint or other chemicals, and follow the manufacturer's instructions for the best results.
