Has nothing to do with a tab, try watching the vid you might actually learn a thing or two
If you are cutting yourself from rubbing the tape in then what does a 1/4" to 1/2 in of tape hanging off the end have to do with it? Its not a barrier at all.
That is your error, also what took Mark nearly 30 seconds to accomplish in the vid takes me less than 5 to do SAFELY every single time
