I hope this doesn't sound like a completely stupid question but my husband and I just purchased a dining table that we didn't do our homework on first before buying. It is a beautiful table, but looking at reviews we are seeing a lot of bad comments due to water marks and finish coming off? Seems like a lot of people are reporting their table being ruined from sweating glasses (not even left overnight), or even hot bowls/mugs leaving rings or causing swelling. We love the table and wondered if there was any suggestions of a sealant we could put on ourselves to protect it from this problem? Or if that would be more trouble than its worth and we should just return the table before we too are sorry. It is the "Bradding Dining Table" from Pier 1 if that makes a difference made from rubberwood, engineered wood, and acacia wood? We don't have a lot of knowledge about wood or finishes and would love to be able to put in a little elbow grease and keep the table and keep it pretty for a long time if possible? Thanks for any insight you all can provide.
