Micro-sol is applied after you've applied the decal to the plane. It helps the decal to snuggle down into places like panel lines, spaces between the wings and control surfaces, etc. When you first put it on, the decal looks like it shrivels up, but just leave it alone. When it dries, it'll be smooth and the decal will have formed itself downa nd around all the surface irregularities. I saw mentioned somewhere that it makes the decals look as though they were painted on.....
Good luck!
