From my own use, I always cleaned dyed and waxed my 330's. It will help prevent them from rusting which can weaken a trap over a period of time. Once you wax a 330, take a knife and cut the wax out of the triger notch to prevent it from firing to quick. 330'S are a Powerful trap,be careful, they have been knowin to break trappers arms. Gloves and Boots are nice for the trapper, but the Beaver dont really pay any mind to human scent.
