Homebrew PCBs

I will visit the chemicals shop tomorrow, and i'd like to prepare for  
future wetting agent/break fluid experiments.
They have a whole host of glycols, which i think are the most likely thing  
to try. After some research propylene glycol seems the least dangerous  
(most others have Xn rating wich i'd rather avoid).
The information i find about wetting and stuff is confusing and  
inconclusive, but not much different from the other glycols. It should  
just boil off during curing with 188C boiling point.

Any ideas/suggestions/recommendations?
