I'm staining a table and some stain got through between the boards of the table when I did the other side. Should I pre-condition over the stain that seeped through? Sand down that stain a bit first and then pre-condition? Just not pre-condition? I should note that as soon as we saw that stain (while the stain on the other side was drying) we wiped it off immediately - so it shouldn't have set it much. Thanks in advance!
