water question/ any experience using MIG acrylic water

I assume most acrylic gel media are pretty much the same.  I get mine at a craft store like Michaels or HL.  I buy brands by price- I have used three brands and they all worked the same.

See Luke Towan's Boulder Creek Railroad website.   He has all sorts of tutorials on scenery, including water.

You are looking at different materials; Acrylics like MiG or Future, and Epoxies like Envirocoat.   

Be careful with Epoxies.  They are exothermic and the heat produced will warp plastic if used in too great a quantity (at one time).  Ask me how I know.  Epoxies also shrink, giving the appearance of water flowing up hill or climbing up a tree trunk

One time I mixed about a half cup of epoxy in a four ounce paper cup.  I got distracted for a couple of minutes and when I looked back at the cup it was smoking and charring.  I had to run outside with it and dropped it to let it harden- waste of two ounces of epoxy!
