I have a long time project pending, building a subwoofer for my basement. The basic construction is complete, but I am lost at finishing it. I need it to be black piano finish but I dont know where to start.
Additionally my subwoofer surface has lot of nicks and dents. Can someone please guide me to the best option I can go for to fill these dents and how to paint this to a smooth finish.
Attaching pictures for reference.
