Another question I have never seen answered: Whether you use only water, or Micro-Set underneath the decal, are you supposed to let it dry completely before putting Micro-Sol or Solvaset on top of it?
I have done it both ways with equal results, although if you put the solvent over a watered-on decal before it sets at least partially, it can walk off to a new position all by itself, as I found one time. Of course, by the time I noticed it, the solvent had done its job and the decal was there to stay!
