When it comes to painting plastic models, there are a variety of paints and top coats to choose from. The type of paint and top coat you use will depend on the desired finish, the type of plastic, and personal preference. Lacquer paints, for example, do not require a primer and can be layered with clear coats and varnish or sanded back for repairs. Acrylic paints, on the other hand, are easy to work with and can be applied by hand or airbrush, but may require a primer and a high-quality clear coat for protection. Enamel paints are also an option and can provide a harder, more durable finish, but may take longer to dry. Ultimately, the best industrial paint top coat for plastic models will depend on the specific project and the desired results.

What You'll Learn
Lacquer paints dry quickly and can be layered with clear coats or varnish
Lacquer paints are a popular choice for plastic models. They are quick-drying and can be layered with clear coats or varnish to add protection and a smooth finish. Lacquer paints are also versatile, as they can be used as primers and can be sanded back if needed. When using lacquer paints, it is important to apply a thin coat first and then a heavier coat to avoid melting the underlying paint.
One option for a lacquer paint top coat is to use a spray lacquer, such as Testors spray lacquer from Hobby Lobby. This can be used over a water-based paint, as mentioned by a user on Reddit. Another option is to use a lacquer-based primer and top coat with a lacquer clear coat. This will provide a chip-resistant finish, ideal for frequently handled plastics.
When choosing a clear coat, it is important to consider the type of paint used. For example, a high-quality clear coat can be used to protect acrylic paints. A clear coat can also be applied over enamel paints, but it is recommended to wait at least 24 hours for the paint to cure first. It is also suggested to use a thinner for airbrushing water-based paints, as it lowers the surface tension of water and makes them easier to spray.
Additionally, there are different types of clear coats available, such as water-based brush and airbrush varnish, polyurethane varnish, and Polycrylic and CAB acrylic lacquer, which give a water-clear finish. Marine Varnish (Epifanes) is another option that gives a high-gloss finish but is better suited for darker colours as it has a golden-brown tint. It is important to note that clear coats can be applied in different ways, such as mist or dust coats, to achieve the desired effect.

Water-based acrylics can be applied by brush or airbrush
Water-based acrylics are a popular choice for painting plastic models. They are easy to work with and can be thinned with water to apply very fine layers. They are also fast-drying, which makes them convenient for layering colours. When using water-based acrylics, it is important to properly prepare the surface of the plastic model by cleaning it with soap and water to ensure that dust particles or contaminants do not get sealed into the paint job. Additionally, a sealing base coat and a top coat are necessary to prevent moisture absorption and ensure adhesion to the plastic surface.
When applying water-based acrylics with a brush, it is crucial to choose the right brush for the painting task and the thickness of the paint. The paint should be mixed thoroughly and loaded onto the brush, removing any excess by wiping it back and forth on a palette. The base colour should be applied using as few strokes as possible to avoid overworking the paint. After painting, brushes should be cleaned with soap and water or a soap-based brush cleaner.
Water-based acrylics can also be applied using an airbrush. To achieve the correct consistency for airbrushing, the acrylic mixture should be thinned with water and, if needed, an acrylic medium. After use, the airbrush should be cleaned with a mixture of soap and water to remove all traces of paint.
It is worth noting that while water-based acrylics are a popular choice for plastic models, they may not be suitable for all projects. If the model will be handled frequently, enamel or oil paint may be a better option as acrylics will require special sealers to withstand repeated handling. Additionally, on non-porous surfaces like plastic, enamel paints may be preferred as they dry without swelling or contracting, resulting in a durable finish.

Enamels are durable and good for secondary paint effects
Enamel paints are highly durable and can withstand moderate to severe impact and abrasion. They are also weather-resistant and fade-resistant, making them ideal for outdoor applications. Enamels are oil-based paints that dry to form a hard, shell-like coating, providing reliable protection even in extreme conditions. They are commonly used on rigid surfaces and objects that don't flex or shift over time, such as metal railings, outdoor furniture, and appliances.
Enamels are an excellent choice for secondary paint effects due to their durability and ability to create specific textures. For example, dry brushing and dust effects can be achieved using enamels, adding depth and realism to a model. Enamels can also be used for weathering effects, creating a worn or aged appearance on surfaces. The hard finish of enamel paints makes them ideal for these secondary techniques, as they can be built up in layers to create the desired texture.
When using enamels for secondary paint effects, it's important to consider the surface preparation. Enamels adhere well to metal surfaces, and sanding with 120-grit sandpaper can improve mechanical adhesion. Additionally, a primer can be applied to enhance adhesion and ensure a smooth finish. Enamels can be thinned with enamel thinners and applied in multiple coats, allowing for gradual build-up and control over the final texture.
Enamels are available in various forms, including spray paint and brush-on paint. Spray enamels are convenient for covering larger areas or achieving a uniform finish. Brush-on enamels offer more precision and are suitable for smaller details or intricate effects. It's worth noting that brush-on enamels require the use of a suitable paintbrush to avoid visible brush strokes.
Enamels are a versatile and durable option for secondary paint effects, offering a range of creative possibilities for model-making and other projects. With their ability to withstand wear and tear, enamels can enhance the longevity and visual appeal of your creations.

Primers increase adhesion to plastic and reduce wiping off paint
When painting plastic model kits, it is important to consider the use of primers to increase adhesion to the plastic surface and reduce the risk of wiping off the paint. Primers are essential in creating a reliable and reproducible surface that enhances bond durability.
Primers are particularly critical when painting on plastic to ensure the paint adheres properly and does not peel off easily. The key is to make the plastic surface chemically and mechanically receptive to the paint. This can be achieved by first cleaning the surface with a water solution and mild detergent, followed by wiping it with isopropyl alcohol. Then, lightly sanding the surface with fine-grit sandpaper can create a roughened surface for better paint adhesion.
Applying a primer specifically designed for plastics, such as Rust-Oleum or Krylon, can significantly improve adhesion. It is recommended to apply multiple thin coats of primer to enhance the bonding. Additionally, using an adhesion promoter, such as 3M Adhesion Promoter 111, can further increase adhesion levels and ensure the best ultimate bond strength.
For plastic model kits, it is important to consider the type of paint used. Acrylic paints and spray paints designed for plastics generally offer better adhesion and durability due to their tuned solvents. However, it is crucial to follow the manufacturer's instructions and allow each layer to cure fully before applying the next coat.
By following these steps of surface preparation, priming, and using the appropriate paint, you can increase adhesion to plastic surfaces and reduce the risk of wiping off the paint during the painting process.
