WebTurnToPoly won't unify normals or duplicate geometry. It just resets the normals while respecting smoothing groups, and whatever other options you pick. If you had mismatched normals you probably had the double faces as well. Try using Xview to identify problems with your mesh. I've been resetting normals with TurnToPoly for years. It works.
