Hi all. I’m just finishing a repro coffee table and would like some opinions. It was pre finished with 3 wiped on coats of dewaxed blond shellac, and I’m wondering about using polyurethane for the last couple coats, for durability. I hate to do it for traditional reasons, and we really dont intend to put drinks on it, but we do have a couple of sometimes overly rambunctious golden retrievers. Was also thinking of maybe a glass top. Any thoughts on durability,repairability,authenticity,etc?
