No, not really, though I have a heat gun, I was too lazy to go get it, I did those with a lighter. I just cut a piece of 3:1 heat shrink tubing and held it even with the bulbous part of the banana plug. Then I held it next to the lighter, not over, as I didn't want black soot marks (I was too lazy to get my nice $60 heat gun from the storage room). voil-la, done. The rest is the heavy duty nylon wire wrap with a patterned section placed over that. (I liked how it made the cable look fat) (the cable is BJC white 12ga).
