When is fine grit, sufficiently fine to apply one's choice of finish? 400? 600? 800? Higher?
I have heard of folks sanding up to 4K grit and have also heard that anything over XXX grit is a waste of time - that about all one does after a certain grit is burnish. If memory serves, that argument was not to bother with anything over about 220 - 300 grit.
For this conversation, let's limit this discussion to wooden bowls/vessels/vases.
When do YOU stop? Inquiring minds and all that.
