Good quality Vulcanite polishes up nicely for many years, but it does take some work. After twenty years or so, some Vulcanite will polish up, to a degree, but it takes more work. It's unusual that decades old Vulcanite holds a polish for many smokes, but I guess it happens. Some restorations on Forums bring totally cruddy Vulcanite back to looking new. If you can use acrylic, especially with pipes of modest weight, it certainly makes maintenance quicker and easier, year after year, if your old teeth bear up.
