Micro Sol setting solution is for the most difficult irregular surfaces you find on models. It completely softens the Microscale Decal allowing it to drape down onto the surface of the model conforming perfectly and without distortion. You can get the most amazing results in seemingly impossible places, because Micro Sol actually makes the decal part of the paint. For that reason you should coat Micro Sol on for only a few seconds and then leave it alone, it does the work. Do not touch until dry as the decal is very soft at this stage and could be easily damaged.For the best results, first apply Micro Set to prepare the surface and enhance adhesion. Make sure the surface is free of particles that could get under and blemish the decal. Then when dry enough so the decal will not move easily, apply Micro Sol with a small flat brush. Apply with as few strokes as possible so as not to disturb the decal. Then just allow to dry. One application works in most cases, but if necessary allow to dry comnpletely and reapply until the deisred effect is achieved. Just by following these simple instructions you should have a perfect professional looking job.
