Other paint types can be used, but are much less common. Lacquer paints can be used for applying fast drying and very hard wearing, chip and scratch resistant coats of paint through an airbrush, but are even more toxic than enamels so are not widely used. Watercolors can be used for weathering effects as they can create dust or dirt effects quickly and can be reactivated with water to remove excess, such as for pinwashing, although these cannot be easily used to paint the full model and require sealing with a varnish after application.
