Despite all the advice, nose oil is an absolute no-no! Ask any top rod maker and they will firmly recommend against the use of any kind of oil as a lubricant on ferrules. Some but not all top rod makers even recommend against paraffin or any type of lubrication as well. Their reason is any lubricant attracts dirt, which will act like sandpaper every time you assemble and disassemble the rod sections.
When it comes to assembling sections, for composite rods just about every top rod mfg recommends inserting the male end with the guides somewhat off-center and gently rotating/pushing the section snuggly into place. When it comes to disassembly, repeat the process rotating/pulling the section the opposite way. This is not a hard twist or push but rather a gentle rotation. However, you never rotate nor twist sections of a bamboo rod together – those sections get pushed straight into place. Also, there should be some space between rod sections.
If you are having problems disassembling rod sections, more than likely you pushed the sections together way too hard. If this happens, take two pieces of ¼ - ½” inner diameter rubber hose each about 5-6 inches long and cut both pieces lengthwise on one side. Slip each piece on a section as close to the ferrule joint as possible and these rubber sleeves will aid in gripping the rod. (This is also very helpful when the rod is damp or wet). This is a trick all bamboo rod makers use. The last thing you want to have happen is your hands slip and bend/break the guides and slice you hand apart. Also, never try and pull the rod sections apart with your hands placed far away from the ferrules because you can easily bend the rod resulting in snapping the ferrule. Keep the grip close.
