If you find that the cut mark at the nose objectionable,you could do as zbass suggests,but it is slow to do that.I think most of the tubes like you want are molded,rather than dipped.If you have a large enough pan,you can dip half a dozen tubes at a time.I have done it in the past,but really didn't see a big time savings.Of course molding still would be the best if you need what you want,but be prepared for a steeper cost,for a minor cosmetic effect.
