anyone ever use this stuff to make 3d BG?

I was searching the web or light weight polyurethane foam and came across this. Has anyone ever used this to make a back ground? I was thinking of making a mold out of a side of a mountain or huge rock. Their casting materials can be pre-dyed and last forever. I think it would be awesome to make a light weight back ground that's already colored with this stuff. Its a bit pricey, but if i can customize the back ground from a rock/mountain/tree trunk of my choice it would be so worth having a one of a kind back ground.

The products are from smooth on. (not sure if i can post a link to their site, so let me know.)

First thing you should do is contact the manufacturer and find out if the product is fish safe.

yes it is, they have a section on making decorations and backgrounds for salter tanks (plastic/rubber/silicone ornaments).

Polygem makes a fish safe epoxy putty that can used to sculpt backgrounds, trees, fish tank inserts like corals. The epoxy is painted with water-based paints and then coated with clear fish safe epoxy paint. A lot of tank decorations are made this way.

Polyurea is fish safe. One big background manufacturer makes rocky backgrounds from polyurea and crushed rock sprayed into silicone molds.
