never used the furnature stuff but i have used gloss cote. As for applying the decal, like CBCN said, just cut out the image or letter you want to use dip it in water (i use twezers) for about 4 or 5 seconds - another 4 or 5 seconds out of the water and you can slide the decal right off. Be careful, the decal is very delicate at this point. Once you have it on the model, i use an unused pensil eraser to gently move it into place. then with a clean dry rag, i dab the excess water off. Again, do this very carefully - before it is dry, you can still knock the decal out of place. Once dry and everything is the way you want it, apply a fine mist of dull cote to seal the deal.
