Can anybody point me to epoxy resin system that does not use a yellow-ish hardener? Possibly something more neutral like blue or something? I am using an amazing epoxy resin system from a German company, but the hardener is yellow and in bright sunlight, you can see the yellow tint on the infused things....Anybody got a clue? Possibly a pigment that I can put in the hardener? I know Koenigsegg uses some kind of pigment to tint the resin to whatever color they want but still keep it transparent...
