PVA is acidic. PVA can be confusing as it may either stand for Polyvinyl acetate, or polyvinyl alcohol.

It could work, I'd test it on a charcoal streamer first. Less things to go wrong and all that. Already pretty fuel deficient too.

Yes, it can react with boric acid. I was actually about to dismiss it completely. I went to wikipedia to make sure I got the compound in glues right and there was a little tidbit about it. I was then reminded of the borate/PVA goo stuff we made in elementary school

Remember that the as well as being a glue PVA is actually a fuel! SO you have to minimise the excess fuel that you add or reformulate the greater mix to account for the fuel in the PVA (but not the water!)

I did hear of some star formulations being developed with reduced dry fuel then a hardening resin as both fuel and binder. -Burned well and was totally waterproof! But there was about 4 - 6% of total resin and the mix was very dry, then pressed into a tool.

Polyvinyl Butyral might be a nice replacement on PVA www.butvar.com
