Once you get them degreased, set them outside to get a coat of rust on them, that way when you dye them the dye will adhere to the traps better. You could also use Speed Dip (a dye you mix with gas or lantern fuel) just make sure do this well in advance so it has time to air out.
DO NOT WAX YOUR CONIBEARS!!!!!!!!!!!!!!!
