THIS PRODUCT IS MENTIONED IN OUR AIRBRUSH TIPS VIDEO:
This is a thinner for water-based hobby colours. If it is difficult to apply with a brush, add a small amount of thinner. For airbrush painting, dilute the paint with a maximum ratio of 1 part thinner to 1 part paint (1:1). This makes it easier to apply as it dries faster than when diluted with water and reduces the repelling phenomenon caused by water. It can also be used to clean tools used with water-based hobby colours.
