Well, I learned a thing or two yesterday when I applied the decal set to my sixties something Torpado...
I learned that the water/soap solution can and should be sprayed onto the tubing surface and the sticky side of the decal. Gently position the decal applying little pressure (pressure will begin the stick to the bike). Once satisfied with position, start in the middle and work out toward the edges to remove air/soap/water from under the decal. Velocals suggested using a smooth credit card as a tool to help push the stuff out from under the decal (works great but do not use the edge - use the flat surface to smooth the decal towards the edges.
Final results in about six hours when I hope to remove the protective application material that is still protecting the decals as they dry into place.
