Has anyone tried this when building a dry rock reef scape and if so would this be comparable to the epoxy putty sticks? Thinking about giving it a try if it’s not too flexible. Going to use the thin superglue with sand powder and accelerator. Was going to epoxy the joints after the glue with this. I used mortar on the cylinder scape but was going to try epoxy this round. I have been looking a the nyos black but if the free form would work it may be a pretty decent savings.
