1. A method of manufacturing an antiperspirant or deodorant product within a container having an application end and an opposite end, the product having an application surface adjacent the application end, the method comprising:(a) delivering a first composition in fluid form through the opposite end of the container to a mold cavity that is defined at least in part by the container, the mold cavity including a removable insert; (b) allowing the first composition to at least partially solidify; (c) removing the insert from the mold cavity to provide a space; and (d) delivering a second composition in fluid form to the space that was occupied by the insert, the second composition contacting the at least partially solidified first composition after delivery without mixing with the at least partially solidified first composition; wherein at least one of the first and second compositions includes an antiperspirant salt and/or a deodorant active ingredient. 2. The method of claim 1 wherein a first portion of the mold cavity defines an application surface of the product.3. The method of claim 2 wherein the first portion is generally dome-shaped.4. The method of claim 1 further comprising inserting the insert into the container prior to step (a).5. The method of claim 2 wherein the first portion of the mold cavity comprises a factory seal portion of the container.6. The method of claim 1 further comprising providing the insert with a flange that fits securely within the opposite end of the container.7. The method of claim 1 further comprising providing the insert with a taper to allow it to be easily removed.8. The method of claim 1 further comprising applying downward pressure to the insert during delivery of the first composition.9. The method of claim 8 further comprising providing the insert with a pressure ridge to sealingly engage an inner surface of the mold cavity.10. The method of claim 1 wherein the first composition and second composition are different colors.11. The method of claim 10 wherein the second composition defines a stripe extending through the first composition, when the application surface of the antiperspirant product is viewed from above.12. The method of claim 1 further comprising (e) allowing the second composition to at least partially solidify.13. The method of claim 12 further comprising (f) applying a package base to close the opposite end of the container before or after the second composition has at least partially solidified.14. The method of claim 13 wherein the package base includes an advancement device constructed to advance the antiperspirant product out of the container.15. A method of manufacturing an antiperspirant or deodorant product having a generally dome-shaped application surface, the method comprising:(a) delivering a first composition in fluid form to an open end of a mold cavity, a first portion of the mold cavity defining the dome-shaped application surface, the mold cavity including a removable insert, (b) allowing the first composition to at least partially solidify; (c) removing the insert from the mold cavity to provide a space; and (d) delivering a second composition in fluid form to the space that was occupied by the insert, the second composition contacting the at least partially solidified first composition after delivery without mixing with the at least partially solidified first composition; wherein at least one of the first and second compositions includes an antiperspirant salt and/or a deodorant active ingredient. 16. The method of claim 15 wherein the insert includes a curved surface shaped to engage the dome-shaped first portion, and the method further comprises inserting the insert into the container, through the open end thereof, until the curved surface sealingly contacts the dome-shaped surface of the first portion.17. The method of claim 16 further comprising providing the insert with a pressure ridge to sealingly engage an inner surface of the mold cavity.18. The method of claim 16 wherein the first composition and second composition are different colors.19. The method of claim 18 wherein the second composition defines a stripe extending through the first composition, when the application surface of the antiperspirant product is viewed from above.20. The method of claim 2 wherein the first portion is defined by a mold member constructed to receive the container in sealing engagement.21. The method of claim 20 wherein the method further comprises mounting the application end on the mold member prior to step (a).22. The method of claim 20 further comprising, prior to step (a), inserting the insert into the mold cavity through an opening in the mold member, the opening being constructed to be sealed by the insert.23. The method of claim 22 further comprising, between steps (c) and (d), sealing the opening with a sealing member having a surface constructed to, with the mold member, define the dome-shaped surface of the first portion.24. The method of claim 20 further comprising, after step (d), (e) allowing the second composition to at least partially solidify, and (f) removing the container from the mold member.25. The method of claim 24 further comprising, after step (f), (g) applying a factory seal to the application surface of the antiperspirant product.26. The method of claim 20 wherein the insert extends from and is integral with the mold member.27. The method of claim 26, further comprising, between steps (c) and (d), applying a factory seal to the application surface of the antiperspirant product.28. The method of claim 1 wherein the insert comprises a material selected from the group consisting of metals, coated metals, plastics and silicone-coated plastics.29. The method of claim 1 wherein the insert comprises a coated metal selected from the group consisting of stainless steel coated with titanium nitride, chromium, or electroless nickel with or without a polytetrafluoroethylene (PTFE) infusion; aluminum coated with aluminum oxide hardcoat anodizing, hardcoat anodizing with a PTFE infusion, or electroless nickel with or without a PTFE infusion; or aluminum plated with nickel or chrome.30. A method of manufacturing an antiperspirant or deodorant product within a container having an application end and an opposite end, the product having an application surface adjacent the application end, the method comprising:(a) delivering a first composition in fluid form through the opposite end of the container to a mold cavity that is defined at least in part by the container, the mold cavity including a removable insert; (b) allowing the first composition to at least partially solidify; (c) removing the insert from the cavity to provide a space; and (d) delivering a second composition in fluid form to the space that was occupied by the insert, the second composition contacting the at least partially solidified first composition after delivery; wherein at least one of the first and second compositions includes an antiperspirant salt and/or a deodorant active ingredient, wherein the insert includes a flange that fits securely within the opposite end of the container, the flange having a taper to allow the insert to be easily removed. 31. The method of claim 30 wherein the first composition and second composition are different colors.
