Micro Set prepares the surface with a special wetting agents that cuts the oils found on new paint and converts the adhesive on the back of the decal to a stronger and more lasting one. Better adhesion by the decal to the model prevents tiny air bells from occurring and results in an invisible carrier film or the so called 'painted on look'. 1 ounce bottle. Made in USA.
