Apply a Red disclosure coat then wet sand and you can immediately see
where you need to sand and where you have sanded enough... Sanding
wet extends the paper life and tends to prevent it clogging... Use good
quality paper (in UK Mirca is good)... Maybe start with 400 or 600 and
stop just before the last of the orange peel is gone... Then apply more
red disclosure and shift to 800, then 1200, then 1500.. Polish with
Farecla G3 then Wax... Craig...

If you want to "check your work", an inexpensive red rubber squeegie
works
well to make the surface dry again (as well as helping remove
"sanding
sludge").
The dry surface you're left with makes it a lot easier to look for
"shiny"
vs. "dull" to see where more sanding may be needed.

I wouldn't wetsand a lot of "natural materials" (wood, paper, bamboo,
leather) unless they had a coating of something or were sealed.
