Wash the plastic miniature with soap and water to remove any residual lubricants or oils
Before painting clear plastic miniature parts, it is important to ensure that the plastic surface is clean and free of any contaminants that may affect the paint's adhesion and overall finish. Washing the plastic miniature with soap and water is an effective way to achieve this. Here is a detailed guide on how to do it:
Firstly, gather your supplies: a mild dish soap, warm water, a soft-bristled brush, and some clean cloths or towels. You may also want to wear gloves to protect your skin from any residual chemicals or paints on the miniature.
Fill a basin or container with warm water and add a few drops of mild dish soap. You can also use a common dishwashing detergent, but ensure it is diluted in water to prevent any potential damage to the plastic. Using a soft-bristled brush, gently scrub the miniature in the soapy water. Pay close attention to crevices and intricate details, as these areas may have built-up lubricants or oils that need to be removed. For hard-to-reach areas, you can use a soft cloth or cotton swab dipped in the soapy water to gently wipe them down.
After thoroughly scrubbing the miniature, rinse it under running warm water to remove any soap residue. Ensure that you direct the water spray away from yourself to avoid getting soaked! Give the miniature a final rinse with plain warm water to ensure no soap residue remains, as this could affect the paint adhesion.
Once the miniature is rinsed, gently shake it to remove excess water, then use a clean, dry cloth to pat it dry. You can also use a hairdryer on a low setting to speed up the drying process, being careful not to melt the plastic. It is important to ensure the miniature is completely dry before proceeding with the next steps of your project.
Washing the plastic miniature with soap and water helps create a clean surface for painting. This step is especially important if you are working with older miniatures or those that have been handled frequently, as they may have accumulated oils, lubricants, or grime from production or storage. By removing these contaminants, you improve the chances of achieving a smooth and even paint finish.

Use masking tape to protect the translucent areas you don't want to paint
When painting clear plastic miniature parts, it's important to consider which areas you want to keep translucent and protect them accordingly. One effective way to do this is by using masking tape.
Before you start painting, make sure to clean your miniature parts by washing them with dish soap and water, especially if they are plastic, to remove any residual lubricants or oils from the manufacturing process. Rinse them off with plain water and let them dry completely.
Now, to protect the translucent areas that you don't want to paint, apply masking tape over those sections. Make sure to smooth the tape down securely so that paint doesn't seep underneath. For smaller or curved areas, you can use poster tack or blue tack to achieve a tighter seal. If you need to create straight lines, use something with a straight edge, like the back of a hobby knife, a toothpick, or tweezers, to press against the tape or tack.
Once you've masked off the areas you want to keep clear, you can proceed with priming and painting the rest of the miniature. Just remember to remove the masking tape carefully before the paint dries completely, to avoid peeling any paint off along with the tape.
By following these steps, you can effectively protect the translucent areas of your clear plastic miniature parts while painting, ensuring that you maintain the desired level of transparency in those sections.

Prime the miniature with a colour primer spray to speed up the painting process
Priming is an essential step before painting a miniature. It provides a surface that paint can adhere to more effectively than plastic, resin, or metal. Primer spray helps the paint stick to the miniature, and it is especially important when using acrylic paint, which does not adhere well when applied directly to plastic.
When priming a miniature with a colour primer spray, it is important to start with a clean surface. Remove any dust, oils, or mould release agents from the miniature. If necessary, wash the miniature with warm, soapy water and let it dry completely. This ensures that the primer adheres well.
When you are ready to prime, shake the spray can thoroughly. Hold the can about 20-30 cm away from the miniature and spray in short bursts, moving the can to avoid spraying the same area for too long. It is important to avoid getting too much primer on the miniature in one go, as this can fill in the fine details. You can always let the primer dry and apply another light coat if needed.
It is also important to consider the colour of the primer. While black primer can provide good coverage, it may require many layers of lighter paint to achieve bright colours. White or light grey primer can be a good choice, as it is easier to cover with darker paint, and it can help you see when you have applied enough primer.

Use a detail paintbrush to paint a highlight colour along the edges of each part of the miniature
Painting a clear plastic miniature can be a challenging task. Here is a step-by-step guide to help you achieve the desired results:
Firstly, it is essential to prepare the miniature for painting. This includes removing any mould lines or flash and attaching the miniature to its base. It is also important to wash the miniature with dish soap and water to ensure the paint will adhere properly. Once cleaned, the miniature should be dried thoroughly before proceeding.
Now, you can begin the painting process. If you wish to preserve the transparency of certain parts, such as wings, you can mask off those areas with tape before painting. For a smooth finish, apply a light coat of clear matte varnish to the unmasked areas, which will help the paint adhere better.
Once the varnish is dry, you can start adding colour. Using a detail paintbrush, carefully paint a highlight colour along the edges of each part of the miniature. Angle your brush and drag it lightly across the edges, creating a subtle base highlight. If you're a beginner, it is recommended to use paint straight from the pot without thinning it, as this will make the process easier. However, thinning the paint can create a nice blending effect with some practice. Be cautious not to overload your brush with too much paint, as this can cause unevenness. If needed, use your base coat colour to clean up any mistakes.
For the smallest details, use a bright highlight colour to accentuate the most prominent features. You can add scratches or other effects by dragging your brush along the edges with a complementary colour. For example, using Brainmatter Beige along the edge of yellow armour can create realistic-looking scratches.
Finally, you can finish the model with a base. If desired, you can continue to add more highlights to enhance the miniature's appearance. Remember, highlighting and shading your miniature will make it stand out and add an element of realism to your creation.

Use a hobby knife to remove mould lines and clean up excess dried glue
Mould lines are small lines that can occur on a model as a result of the moulding process. They can be removed with a hobby knife, but this requires careful precision to avoid cutting off parts of the model itself. For beginners, it is recommended to use a mould line remover tool, as this is less likely to damage the model. To remove mould lines, gently scrape the tool across the line.
When using a hobby knife, it is important to be cautious and gentle to avoid accidental cuts or dents in the model. A flat scalpel blade can be used, but it is easy to accidentally damage the model with this type of blade. Instead, a tool with a triangular blade, such as the Micro-Mark Seam Scraper, can be useful as it can reach tight spaces and is less likely to cause accidental damage.
To remove excess dried glue, a hobby knife can be used to carefully scrape away the glue. Paper towels can also be useful for wiping away excess glue before it dries. It is important to be gentle when removing excess glue to avoid damaging the model.
In addition to a hobby knife, there are several other tools that can be used to remove mould lines. Sanding sponges and emery boards can be cut into strips and used to remove mould lines and other imperfections from rounded surfaces. Toothbrushes can be used to remove excess plastic flakes that stick to the model during the removal process.
