Does anyone have successful experience filling in small voids (i.e. 1/8 wide by 1/8 deep by 1/2 long) with Poly or Laquer? The wood is Claro Walnut Burl. CA has been an utter failure. It takes forever to dry and ends up getting soaked up into the wood. I do not want to use epoxy with coffee grinds. I want it to be clear as I think voids like this add tons of character. When I mix my 2 part epoxy, it gets a little 'bubbly' so I don't want to try that straight. Would just Laquer or Poly work? thanks!
