Thanks.
Yes, solder mask is how you call it. Sorry I couldn´t remember. Well, 
using a sharp blade seems obvious, but the traces are really thin, 
hence why I thought of dissolving the mask instead of scraping (and 
the traces going with it). 
I´m going to try anyway. There´s enough area for mistakes and I can 
make the bridges with wirewrap wire.
