Share 'Pore-filling around bridge mask?'

Hello Everyone, I'm very new and starting my first build, but this will be the 3rd time finishing (or refinishing) an instrument. I'm in the process of planning out my build and have one question: How do you pore-fill/level-sand with the bridge tape-mask on the top? I have followed this exact process to great success with my first two pore-fills using Z-Poxy: https://www.youtube.com/watch?v=gc5…
