Dyeing and waxing Belisle and leghold traps

Does anyone have experience with dyeing and waxing Belisle or leghold traps? Alternatively, does anyone know if there are any companies that would do this?

We used to hot-dip Fenn traps years ago using paraffin wax to stop them rusting, it worked OK for a while. Wax blocks are available to buy from beekeeping supplies websites. Be careful with the hot wax, preferably do it outside with safety glasses on.
