I bought some jet dry and put a little in the water I use to rinse out the molds to prep for hydrostone casting. It's been working great.
I was wondering if I could use this same Jet Dry as a flow aid for white glue & water mixture for sealing terrain, also as flow aid for diy washes.

Yep. That's exactly what I use. It works great!

The other flow aid commonly used, is liquid dish soap, like Palmolive, Dawn, etc. It takes very little. The difference, of course, is viscosity: liquid dish soaps are very thick, and viscous, where Jet Dry is very runny, and not viscous at all. I've used dish soap, but I have not tried Jet Dry -- yet... I've tried mixing in dish soap with my bottles of PVA Glue, to get it to lay flat, rather than beading up, when I paint it on my vinyl floor tile bases prior to swirling them in my colored sand mixtures -- doesn't work very well, it alays beads up within seconds, which leads to uneven coverage (and a 2nd, or 3rd, application and swirl...). I've always suspected the PVA's viscosity prevented the equally viscous dish soap from mixing properly. Will have to try this. Soon. Thanks for posting on this, jennifer and drwillsdc ! Cheers!

Dont thank me, thank the magic of the internet. I think the youtube channel was rubbish in rubbish out. He puts his PVA mix in a spray bottle and sprays it on. I imagine it requires a few coats, but once its on there...presto. Just to be clear, I use an eyedropper, and yes, jet dry is VERY runny and will get everywhere.

You use an eyedropper to apply the PVA glue and water mixture. That is what I was thinking of using with this jet dry. Mind sharing your recipe for your mixture? This is for sealing right?

Sealing , affixing, pretty much anything. What I generally do is dip the base or whatever in the flock or sand, then add the pva mix on top. I use a mix that is about 50% pva and 50% water with a tablespoon or 2 of jet dry mixed in. I try it and if need be, add more jet dry till it flows down through the flock without beading up. Hope that helps.

I use an eye dropper bottle that's about half and again the size of a bottle of whiteout. Basically, experiment with the proportions till you find what works.

That's a HUGE percentage I used like 1 tbsp in an entire large spray bottle for wet water for hydrostone casts.

Maybe that didn't describe it properly. I don't have a set amount I use. I utilize the old "by guess and by golly" method. I add drops till I get the result I want. Sorry for the confusion.

You can also check out how model railroad enthusiasts seal their scenery. If I remember correctly they often will spray rubbing alcohol on the scenery first, then use an eye dropper with the PVA glue/water mix to drop onto the scenery to seal it.
For Hirst Arts molds, I have been using the 'wet' water method using Jet Dry, but a while ago I bought a flow agent, don't remember the name, but will try and remember to look for the bottle when I get home tonight. It is actually formulated to help plasters/hyrdostone products to flow into all of the cracks and crevices of a mold. Supposed to also reduce the amount of air bubbles you get, if I remember correctly.
