I could add a couple of ideas to this. I have used Sealtex track bandage with good results. It is latex rubber that only sticks to itself. Since it is rubber, it won't slip when wrapped tight & can be removed with no marks left. As an added benefit, it is tan in color, so it doesn't show thru if you have any gaps. I cut a strip about 1/4 in wide. I bought from ebay. Don Brown uses blue painters tape with good results. He likes it because it resists moisture & won't run any color. Buck
