Can you fill the imperfections such as small nicks with bees wax and then cover it with shellac? Will the shellac bond and be permanent or will it flake off at some point?

I have tried Famowood filler, dust and CA, and others, but I have not been able to get a good color match. I put some bees wax on some test imperfections and used a cabinet scraper to level it with the surface. The surface looks great. I am concerned that the upcoming coat of shellac will not adhere and be permanent. Any comments or suggestions from those of you who are much wiser in these type of things?
