Finishing a Tall clock made from Walnut and have been trying to fill the pores with shellac with is what the finish is. I have been working at it for awhile LOTS of coats and sanding down and recoatng. Don't really fill like I'm making a lot of progress. Is there a type of clear wood filler I can use. I have seen some online but some of the review are not good. When I say a lot of coats, like maybe 10 coats of shellac.
Suggestions?
