I bought a new set of double coils this year because I have been out of trapping for a few years now. I went through the normal routine of rebuilding the traps after receiving them and boiled them to get the oils out of the metal. I floated the trap wax on water and pulled the traps up through them. Within one week all of them had rust on them and I hadn't even put them out yet. Any suggestions? What am I forgeting?
