for better adhesion
Micro Set is a very versatile decal setting solution that does several things to the decal to improve application. Micro Set should be applied to the model where you will be sliding off the decal. Micro Set prepares the surface with special wetting agents that cut the oils in new paint and convert the adhesive on the back of the decal to a stronger and longer lasting one. Finally, Micro Set slightly softens the decal film to make it more flexible so that it can conform better to the model's surface. The decal's better adhesion to the model prevents tiny air bells from occurring and results in an invisible carrier film or the so called "paint on look".
To apply Micro Set, use a soft, flat artist's brush and apply Micro Set where you are going to apply the decal. Next slide off the decal. Use a small pointed tip synthetic bristle brush carefully to position the decal. Blot the decal carefully with tissue or paper toweling so as not to move it and allow to dry overnight. It is then ready for a protective coat of Micro Coat Flat, Satin, or Gloss.
