Speed Performance : polish the carver board

Hello Mates,

I read on this forum that to increase the Carver performance by decreasing the resistance, there are multiples tips :

  1. shorter fins (which one?)
  2. polish bottom
  3. use the paddle (like SUP paddle) this will significantly increase speed if you add paddling not just standing
  4. use pumping technique

The question about polishing the board is simply how to do that?
Can anyone do it? Does it need a professional?
