In short, determine what you will need in the way of weather resistance, chemical compatibility and the fineness of the line before reaching for a roll of masking tape. 3M and other tape manufacturers provide detailed sales information for all of their products, making the selection process relatively easy.
Lastly, here’s a tip: The natural tendency when removing tape is to pull it at 90 degrees to the surface. That’s fine if the surface is gelcoat, but if, for instance, it’s an old varnished sole or recently applied enamel paint, there’s a risk of pulling the coating with it. To avoid that, pull the tape back closer to 180 degrees. By doing so, you’ll create less stress on the coating’s bond.
