So I am ready to put a Tru-Oil finish on a mahogany/maple bass and need to find a grain filler for the mahogany. I can't find anyone in the area who carries Birchwood Casey's sealer & filler, which was my first choice. I tryed using some minwax wood filler on scrap and soon discovered that it wasn't clear and was made for being stained. I was thinking about sanding sealer, but didn't know if it would work with Tru-Oil. I would like to be able to use something from Home Depot or Woodcraft instead waiting for something to be shipped. Any suggestions?
