Thank you for your response!! I will definitely have a look at this.http://products.sunshinesupply.com/...for-testing-purposes-epro-ecoline-r-membrane? I'm trying this product, I don't have the sulcata yet but will be getting a large male... I can tell you from applying it that is has a tenacious bond after it drys. i did a sample on a piece of plywood and I tried to separate it from the plywood and you have to destroy the plywood to get it to remove... only time will tell but I hope it will have good longevity... I did this instead of horse stall mats... It is stocked at commercial construction supply stores...
