So you rust your traps to take the dye. Then you dye the traps In a hot dye solution. Then you take the traps out and hang to dry and they begin to rust as they dry. Then you cover the dye with wax.
But If that gives you confidence In your catch rate then that's what you should do.
No I don't rust my traps to dye, but I do dye traps that are already rusted. I've a couple traps that are fifteen years old and still have a lot of silver showing, unlike their littermates they never rusted much, all those traps bought at that time I waxed brand new and went to using. Those couple apparently never caught much/had the wax knocked off of them so they never developed rust in a lot of places to take the dye. They are ran through the dye pot and waxed every year, but they are kind of mottled black and silver gray because the dye doesn't take on the clean steel.
And I've some traps that were dyed and waxed fifteen years ago (with the wax melted on top of the water of the dye pot, so no chance to "dry" before being waxed) and haven't been used since, just hung on the side of the shed. (Bunch of Victor #3 dbls beaver traps, I don't trap near as many beaver as I used to, and always set all my #4s and B&Ls first because I like them better, and haven't had to break into a few dozen of my #3 spares) Those traps are as nice a black without a drop of rust on them, as they were the day I pulled them out of the pot. So I will argue the dye and wax does protect them and they do not begin to rust as soon as you pull them out.
