Most time Future will lay them down with no problem, but occasionally I have to use it when Future does not lay them down or I have a thick decal I know will not lay down without some help. Works better than Micro products. BE CAREFUL - THIS STUFF IS POWERFUL. Have your decal placed where you want it, cause on most decals once applied, you will not move the decal as it will be destroyed. It will do an outstanding job of putting decals down. For most decals, I dip a 001 brush into it, lightly apply some on the decal, that is just get the decal moist on the surface, then immediately follow up by lightly blotting the decal with a sturdy tissue or soft paper towel moistened with water to remove any excess. Let sit, the decal will be plastered to the paint. Really thick decals you can let it sit on without blotting with the tissue, but best to try it out on a scrap decal first. A little practice and experience, you'll love it.
