Japan was early to adopt acrylic paints in modelling, and Gunze Sangyo has been in the forefront of the development. Gunze Sangyo Aqueous colours are still some of the finest flowing acrylic airbrush paints available. Thinning may be accomplished with either isopropyl alcohol or Gunze thinner, both producing super-thin, smooth coats. Gunze Sangyo acrylic numbers ar often given in Japanese kit instructions (i.e. Hasegawa) as "black numbers in white boxes". The paints in Gunze "Mr colour" range, often denoted as "white numbers in black boxes", use different numbering system, and most often do not match the shades given here.
