Supplies ordered.  I'll post up when I give this a try.  It should be good for a few laughs.

Too bad i didnt see this earlier, I could have hooked you up with the PVA. Watch out with that shit though. It is a pregnant dog to get into solution leave alone into a sprayer (if thats what you plan on using).

Why is PVA difficult to get into solution?  Please elaborate.

I have a parts sprayer (tube attached to parts cleaner) that I've seen used to apply PVA release agent.

PVA has low solubility in non-volatile solvents. Depends on what you are trying to dissolve it with. If you bought a pre-made solution, you obviously will not have a problem. In water, a 20% solution takes forever to make. You will have to put it on constant stir with low heat in order to get it into solution. Usually takes overnight and a stir/hot plate and some magnetic stir bars.

If you are making a lower percent solution w/v then you might have better luck. Let me know if you have any issues and I can give you some 20%w/v that would be usuable.

I will dissolve it in aqueous ethanol.  I do have some inside information though.
