What do you put on your cork tape???

[yoda1560]

I recently bought a Calstar 800L cork taped. People have been telling me to put electrical tape and others are telling me to put shrink tube on the cork before placing on the reel clamp. Personally, I found it hard to find the right size shrink tube. What works for you??? Please share with a puzzled fisherman. Thanks!!!<br><br>
