How to properly mix epoxy resin and hardener(video tutorial)

Hi all,
in this video I am going to show you how to properly mix epoxy resin and hardener as some people, including me in the beginning, are a bit frustrated about this procedure.
Before you start, read properly the instruction on the resin container as each manufaturer has its own mixing ration. If you put too little of the hardener, your resin will take longer to cure. But if you put too much, then it may never cure. So read instructions before you start :)
