Have you done a second coat of epoxy on this yet? I'm guessing its for pore filling and coverage of any sand throughs...

I bought System Three Clear Coat (low viscosity). It's pretty close to something like heavy water. I still have a long way to go before I get to this stage, but I wanted to see if you'd had a chance to tackle the second coat yet, and get your take on the pore filling properties of that second coat.
