The finish on my maple dresser's top was ruined when a bottle of nail polish remover was spilled on it. When I wiped up the remover it took the finish off. There is no stain. It looks like just a clear matte finish (polyurethane?). Can I just sand down the whole top and apply polyurethane? Should I strip of the remaining finish first and then sand? Someone suggested restorafinish. Would this work on a fairly large area?
