Hello! Resin newbie here. 🙂
I have been casting pieces with epoxy resin and I have read and experienced first hand that they never truly harden to an impenetrable finish. If I apply enough pressure I can still dent them with my fingernails and such.
So I am looking for something that I can coat them in that would give the surface a little more hardness and durability, something with a clear gloss finish. Would something like a varnish work? Any kind of recommendation would be awesome. Thanks!
