Plastic models should never be exposed to direct sunlight. The ultraviolet rays from the sun can cause the plastic material to break down over time, affecting how the model looks once it's finished. Instead, expose plastic models to natural light during the day and an artificial light at night.

It is not necessary to seal plastic models. However, if you do want to protect the finish, there are products available for this purpose.

Car painters use aerosol products to apply their paints. These products are usually mixed on site before use. They usually include some type of alcohol as a solvent and dye or pigment to color the paint. The types of dyes used by car painters are similar to those used by textile artists; these dyes are available in solid form or dissolved in water or alcohol. Painters often add thinners to their mixes to reduce the viscosity of the paint so it can be applied easily in coats of appropriate thickness.

Alcohol has a very low boiling point (78°F/32°C), so it's not advisable to mix car paint in anything other than an industrial-grade blender.
