We just sanded down an antique oak kitchen table top and then lightly stained it, then put on 6 hand rubbed coats of Formby's Tung Oil Finish over this. It looks nice and I thought this would provide good water protection, but after just a few days of using the table top it is showing light white watermarks from glasses already, that will not completely come off. :huh: I really like the look of the finish = low gloss but feel like we must coat it now with something else to keep the surface looking good. I got some "low gloss" Cabot polyurethane to try over the surface, and put in on the spare table leaf to see how I liked it. I don't though, as it looks too thick with tiny, tiny bubbles in the surface and pretty glossy looking. I sanded with 600 grit paper that did dull it down some, but really don't like the look of it compared to the Forby's "Tung Oil" finish. I realize that this is not a true Tung Oil finish anyways, but had found good reviews on it. Any suggestions on what to do now. I just want it good and waterproof so that I don't have to worry about water spots. Is there another type of varnish that would work better for this or? I don't want to strip it all down to start over if I don't have to either.
