It's Ruff sanding, so i use a 1/2-round or round file
with a rather Heavy groove ; clean Before
the grooves full, and i do it with More water and a file
brush. It only sticks if you don't clean every very often.
Rotate the file every other pass.

Same goes for the Wet & Dry sandpaper, don't let the grit
get filled or ya got to toss that piece.

Wear Very Wet cotton gloves and use them to keep your
work wet; that also helps to keep your girlfriend happy
if you use your hands a Lot !!
