Hi Tony,
Sounds like you could be using too much. I know its tempting to get the surface 'wet' for the decal/transfer to go onto.
Microset is the wetting agent, but it does not mean that the surface has to be soaking wet. I use a largish brush and paint Microset on the area to be transfered/decalled. For me it does not seem to matter if that application has started to dry or has 'run off' before I get to the point of application. I think the chemical process has already begun and has prepared the surface to remove air between the two.
Once you have applied the Microsol which softens and helps the transfer/decal to bed down and it has dried, you should wash off excess of both soloutions prior to varnishing anyway. So the fact you get 'pooling' somewhere shouldn't really matter, other than you are having to remove unecessary amounts.
