Okay. But why not leave the dirty trap at the dirty set, and make a new fresh set outside the catch circle?
But, that may be a moot point.
No matter what you put on the trap, it will be contaminated after an animal is caught. You're going to have to clean that trap up, before you make a new set with it. You can boil dipped traps to clean them up. You're not saving any clean up costs.
Now let's say you have your dipped trap cleaned up. It may have some, maybe even most, of the dip on it, but it will be nicked and scratched and those places will rust. I am primarily worried about rust from deterioration point. It could be really bad if you resued that trap with a corrosive antifreeze like salt or calcium chloride. It is up to you how much rusting you can tolerate on a reset trap.
In my estimation, trying to redip traps during the cold weather of trapping season would be unwise. Dip just doesn’t dry quickly in cold weather. You can, as you know, rewax a trap and use it the next day.
The only kind of coating that would hold up to any extent would be the powder coatings that we talked about on here a while ago. But that would be expensive, and it would have to be done when the traps were brand new.
So, the question is how much rust can you stand?
