Use white caulk and then repaint the moulding. The quickest and easiest fix.I don't know how to do shit, but it seems like a lot of you do. I would like to re-fill the spaces that have formed in a number of spots between the different pieces of wood molding in my basement. The molding is all white, so can I just buy white caulk and fill the spaces and leave it at that, or will it look shitty if I don't repaint as well?
