Sandpaper vs. Liquid Sandpaper/Deglosser

Are you thinking of refurbishing an old piece of furniture this spring or pick up a used item that needs a bit of TLC? If so, consider the pros and cons of using sandpaper and liquid sandpaper/deglosser. Both help prep your item for re-finishing (such as a new layer of primer and paint).

Are you planning on refurbishing anything soon? If so, what are you planning on using to prep your item?
