I recently found three decks in my studio that I'd started painting around five years ago and never finished.

 

Covered with layer upon layer of acrylic, it seemed impossible to return the board back to it's original state.

I quickly realised that sanding by hand was going nowhere, so I headed out to find a more suitable electric sander and after much perseverance, the wood started to appear.
