Probs can use dollar tree clay shaping tools from hobby department....or gloves......I use my fingers....yes it does bond.....O_O Goo Gone takes it off tho....also a dollar tree purchase.....literally your aqua scape tools, and supplies can be all dollar tree. Glue, goo gone, shaping tools, baking soda, vinyl gloves, I would use both liquid and gel super glu. The liquid can be used to squirt up inside areas where baking soda is, under the piece and will bond.
. Try it out on small pieces if you have some laying around man. It's pretty fun.As a matter of fact just grab some stones from your back yard....test it out.....see the tensile stength, and you can even test it over time with 0 detriment to tank stuff......Even try bricks....same porosity as your live rock to be honest.
