I looked at some past threads and I am not clear on parts of this issue. As I check the internet, I see that I cannot purchase Envirotex at Lowe's or at Home Depot. I can purchase Envirotex at Michael's and maybe Hobby Lobby. True or not? Anyone with actual experience? Envirotex Lite seems to be the only thing available? I guess Envirotex was too toxic. (Probably was.) Some have use Famowood? Is this a type of Envirotex substitute? Thanks for the info. I am not so much interested in its application or use, but the actual purchase of the item seems to be in doubt, at least in South Texas. Thanks again.
