I used this to make my first river table. It turned out well enough, but not perfect. I watched videos where ppl just poured the epoxy in all at once... DONT DO THIS!!! It quickly started to smoke and let off some seriously terrible gasses. This is called uncontrolled exotherm, and it nearly ruined everything. Pour it in layers!!!! And let it cool off entirely between layers!!! I would t go more than about a half inch thick per layer... once bitten. Aside from that, I’ve used this product a few times, both for deep fill and as a top coat, and it works very very well. Another warning!! Yes, it cures in 72 hrs depending on ambient temp and relative humidity... BUT... it can take up to a year or more to harden completely!!! It can scratch and whatnot VERY easily for the first month or so- so make sure to put something soft between the top coat and your stuff for a few months. I’ll see if I can’t add some photos... because despite all my mistakes, it looks amazing.
