ok, here's the thing I've finally finished the fake rock backdrop for my viv and have applied the first coats of polyester resin, when I find this website
http://www.garf.org/140.gallon.html#PAINT it states that polyester resin is not safe for aquarium (in my case viv) use, however I have read elsewhere that it is safe. so now I am not sure if I have to start over, proceed as planned, or can I seal the whole thing polyester and all with an epoxy for portable water tanks (which I had no idea even existed, and neather did the sherwin williams rep that I consulted) thanks for any help
