Water-thinnable, meaning that you can wash the tools with plain Water and don't need any special thinners. However, if the paint dries you can usually remove it with rubbing alcohol. If you need the paint thinner, you can dilute it slightly with Water. But thinning also reduces the luminosity.

Shake or stir the bottle well. Apply the paint to a clean, dry surface and let it dry. If one coat is not enough, apply a second coat. Wash the work equipment with Water. Prevent it from drying.

Paint does not cover well. Paint dark surfaces with white paint. Sometimes more coats are enough.

Storage
Store in tightly sealed containers at room temperature. Avoid direct sunlight and high temperatures. Do not allow to freeze. Thickening of the paint during prolonged storage is not detrimental.
