PERMA STONE!!!
well well well so i made some calls to the 2 companies in question and may i say one was very nice one was a lil bit rude

but dont worry the nice one is the answer
ACTIVA brand acni certified perma-stone is the answer
its a quick set plaster that is non toxic and weather proof/water proof. it sets up and is de-moldable in 30 min (meaning hard enough to work with in 30 min)
i am working with the supplier who is also in texas


they are about 5 hours north of me and this means shipping wont be to expencive at all for me to get 50lb bags. if i do so then i can distribute it to you guys for as cheep as i possibly can if any one wants to take me up on that offer.
so..... habacrete can kiss our butts. i have found a non toxic, water/weather proof solution to habacrete.
and guess what , its not 10$ a pound
field testing pending. i'm heading to a local hobby store to pick up a small quantity of it. but guess what, the company offered to send me a sample too! so they are very cool!
