clear filler for large open knots?
I am having a kitchen island top built out of some really cool old oak boards (2" thick) I pulled out of the hay loft of my ooooold barn. I had them remilled, to some degree, to straighten them and remove the "gunk" but they still have plenty of "character"! I had barely enough for the top so wasn't able to cut out a few big open knots in one board in particlar. The guy at the lumber yard said there's a product that I can use to fill these that dries clear, hard, and smooth, but he didn't know what it was called, naturally. I sure hope he is right because if not, I'll be vaccuming a lot of crumbs out of those deep holes! Any suggestions?? TIA!
