I bought this Sun Coral about 3 months ago......and it is already taking over the rock that it came to me on. So I wanted to mount it onto a bigger rock.......but Im having a trouble doing it. I tried super glue, but I couldnt get it to work. So I saw that I have some left over, 2 part epoxy putty (the kind that you have to knead the 2 parts together). Would this be OK to use?
