Conventional dying is more of a tradition to me than a need in some ways. If I'm land trapping canines, I feel a clean trap with a good coat of wax will cover the the scent department. No need for dye as the trap is buried under ground and nothing can see it. If I were to buy a new dozen land traps, I would boil off the factory oil and just wax them with clean wax. Why rust them to get a coat of dye that the animal can't see? Normally you would get a light coat of rust on the traps to get your dye to stick. I don't see a reason to start the rust process in the first place. I have a lot of old traps that will get dyed every season just because I love the look of them, but as I have went through the years I don't see too many reasons behind it. With that said I can't stand to set a bright silver trap in the water wether it's at a pocket set or a blind set for any critter. My water traps have to be camo in some fashion. So yes, I will still boil, dye and wax all my water traps. I would just use spray paint on the footholds (I do on my conis) but you can't wax a spray painted trap. Wax is your best friend on land for scent, and your best friend to prevent rust in the water. To any of you with limited experience I would advise against waxing any body grippers (conis)
I have dipped parts of 110's in wax with good results but would never wax a large coni like a 330. You are just asking for trouble.
