I have a 16oz bottle of gflex hardener and resin thats almost full. Ive probably done three or four knives with it so there is not much gone. I found I am allergic to it so I cant use it and would hate for it to go to waste. Im looking to trade it for something else I can use like steel, wood, belts, etc. If your interested let me know what ya got and we can work it out
