What is the difference between all the types of model paint?

Acrylic

Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water soluble but become water resistant when dry. Depending on the suspension agent used in the paint, some acrylics can be thinned with water, but it is generally best to use the manufacturers recommended thinner to avoid potential problems.

Enamel

Enamel paint is usually used to describe oil based paints, which air-dries to a hard finish. Consequently they are more resilient to hard wear and tear (scratches) and temperature variations. Enamel paint can be thinned with enamel thinners, which can also be used to clean brushes and equipment. Enamel paint IS NOT water soluble, and water CANNOT be used to thin or clean enamel paint.

Lacquer

Lacquer paint is generally referred to as an alcohol based paint, and specific lacquer thinners must be used to thin the lacquer paint and to clean equipment after use. When dry, lacquer paint forms hard and tough surface which is resistant to scratching and temperature variations

Mixing of paint

The different types of paint cannot be mixed when wet, and it is strongly advised that different brands of the same type of paint are not mixed when wet. Variations in the chemical composition of the paints among manufacturers usually results in the different brands of paint being incomparable with each other when wet. In other words, follow the manufacturer’s recommendations for best results.
