The stuff i use is called Epoxy Finishing Resin - i would post a pic but i have run out and need more!
I am pretty sure its the stuff used for working with fibreglass - it goes on runny like paint but sets rock hard in a few hours. VERY different to normal epoxy resin which is like a lumpy glue - i bought this first in error (no use at all) but its great for frags....i have stuck all my loose zoas and rics to lumps of LR ruble with the stuff
