In the world of plumbers and pipe fitters around the world you will find tape and composite advocates. Each has their pros and cons and their own tips (e.g. if you always need to be in touch, use a connection unless it's plastic). Thing is, if you're using Compound, it's a great brand. It spreads evenly and provides a clean and tight seal. It's the perfect size to simply "keep handy" when duct tape isn't your choice.
