Hey guys and girls I was just wondering where abouts I could fine the poly product to make rockwalls were I would find it in gippsland dandenong or caulfield. And wat exactly I am asking for when ordering that would be great. Sorry if there is heaps of this already posted but I'm using my phone and it'd really hard to do searches using it. Also is it the same product u would use to do a fish tank design one cheers guys
