If you are going to sand the faired areas or the bottom in total for smoothness, be sure to use a long board, see 3m Longboard
, as that's the only way to remove the high points. You also need to use a long board if you actually shape your foils, which is pretty unusual outside of one-design racing.
This is an ugly and painful job best done by teenagers.
