I was reading about this new spray-on concrete stuff called Grancrete I though it might be a good way to make a flex free sub box. What do you guys think about it? It has to be easier then working with real concrete.

 

thats interesting stuff i havent heard about that stuff but i think that would work fine deadenin stuff and ya making the box stronger but where would you get that stuff and what does it cost

 

I'm not sure if it is out yet? I was reading about it in popular science. It is suppose to be cheaper and stronger then concrete and you spray it over a styrofoam frame. I figure you should be able to make some creative designs easily out of styrofoam.
