I'm interested in how it does what it's supposed to do. It sounds like you've blended a couple of fluids without much thought or knowledge and found it seems to work rather than working from the ground up so to speak. Are you blending them yourself?
I come from a printing background where surface tension of pure water is altered using isopropanol. Obviously you haven't gone down this route so it seems more likely it's detergent/soap based. Good luck though - I'm going to watch this thread a bit longer and see how everyone gets on.
intresting,in summer try propanol a for slower drying times dave,iso is ok but not the be all,as you know its a wetting agent for the printing industustry to make the ink flow better(the use of di water has improved this process even further now).
vision amongst other "mixes"that have been developed have ALL been built from the ground up not just flash from sainsbury's and a bit of fairy added,it takes a long long while to formulate something like vision and the others,a lot of research not just by ourselves but we are aided by chemists as and when we need them,as for one or two tails?i'd go one tail and two heads to answer the question but why two heads when you can cleverly use just the one?
