The way I do mine is to cut strips of paper towel and wrap the cap until it is a snug fit in the tube. If the leads need to be made longer I add on the new lead so the joint will be within the body of the cap. Then I fill the ends with bees wax. I thought about using the glue gun but then I thought it might be tough for the future restorer to get apart without damaging the paper tube. The bees wax does look original as well.
