After trying several other brands of epoxy resin, I discovered ArtResin a couple years ago and have vowed never to use another one. It creates a beautiful finish for my art, but more importantly, the fumes are minimal and it's non-toxic. Other products gave me headaches and filled my whole house with fumes for days - this truly does feel like a much safer product. Because I used it about twice a week for several hours at a time, that is really important to me and my family. Also - the yellowing is barely noticeable...far superior to other brands!
