nice tutorial cheers Rob. Wow that epoxy looks up to 5-6mm thick.
So when you sand with finer paper will it be transparent ?

I'm very interested in how you prepped and poured the epoxy. I am using some epoxy resin for a different project. A new outdoor bar I am covering the bar top with beer caps and want to fill all the gaps with clear epoxy resin.
I'll ask some more questions when I collect enough lids !
