Hello, When preparing wood with epoxi prior to varnish,: after the epoxi is cured, clean it with water and soap and rince a lot, this step will remove all wax residu, it need to be done before you sand or varnish. I am sure every one and you know this already, but i just cant keep my mouth shut on this. I paid a lot of elbow greace for that knowledge.Again, excuse my english.David
