I refinished a dinner table that was badly damaged by water glass marks, hot food dishes, and children abusing the surface. Nice oak table made by a major manufacturer but it had a cheap lacquer spray finish. I scraped it down to the wood, stained to match the skirt and legs which were still like new, then applied three coats of Min-Wax polyurethane. After 30 years of hard use by 4 children and 2 adults it still looks like new. After 30 days all clear finishes are food safe by US federal law. I still use poly when I need a lasting finish for indoor use.
