Hi and thanks Peter,

I changed brands of resin maybe half a dozen times when I first started 3 or so years ago. For some time now I use a casting resin called Oakfield Clear Clarity Cast epoxy resin. I love it, the woman who owns the business and also makes huge resin tables etc, is very helpfull. She's answered a heap of my questions over time. That is the casting resin which I pour to make the rivers etc.

For the flood coat on top I use Stone Coat Countertop resin, a 1:1 mix. 2 coats, first coat is like a sealing coat, sand that back after 24 hours to 240 grit. Second coat sets like glass, amazing.
