Got it to protect the finish of my Godin.
Managed to place it with a good result but it was not an easy task, it is very sticky so I had to be very careful and rehearse my moves beforehand.
It's big 20x25cm so you can cover most of your picking area, it comes with templates to cut different shapes, I didn't use them but did cut a little bit off and I'd recommend to use a very sharp stanley knife and rulers, scissors will leave uneven edges, they can be filed down a bit though.
