Jay,
I am very interested in this subject of creating fake rock, walls, etc., and have been looking for information, mostly, about how toxic these materials are or not, and durability. Yes, they look great wen just finished, but as Dale noted, they just seem to fall apart after some time.
If there are alternatives (inert materials that do not decompose, etc.,) I would like to find the best sources to learn about them and would very much appreciate it of you could point me in the right direction.
If you would rather discuss it privately via email, please feel free to email me (I tried looking up your profile but there is no way to send a private message it seems.)
Thank you in advance for any possible help.
