Micro Set - Decal Setting Solution

Micro Set should be applied to the surface of the model where you will be sliding off the decal. Micro Set prepares the surface with special wetting agents that cuts the oils in new paint and converts the adhesive on the back of the decal to a stronger and more lasting one.

And finally, Micro Set slightly softens the decals film to make it more flexible so that it can conform better to the model's surface. 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

The Difference Between Micro Sol and Micro Set

Micro Set is used to prepare the surface of the model where you want to place your decal, so you can slide your decal off it's paper and onto the surface where you want it, and reposition it a little until you are happy. Wick off excess fluid using some paper or a sponge or something.

Micro Sol will "melt" the decal into paint - making it soften and snuggle into cracks and ridges etc. Once you have applied the Micro sol over the decal after it has been placed on the model, hands off - do not try to move the decal or wick off excess fluid - the decal will fall apart and be ruined.
