Greetings!
I think before sanding a new table, I would try waxing it,
Any car wax or furniture polish should help.
If that isn't sufficient enough, then you could try sanding it
but, I would definitely use a very FINE grit and would not
over do it.
I'm not an expert on this subject but, that's my thoughts for you to ponder.
God Bless! Spirithorse
