I've read that some of you use this technique to fill in cracks/voids in your turnings. I'd like to adapt it to filling in engraving done with my cnc router. So far my tests have not been encouraging.
My method is to spray the engraving with shellac, let dry, fill engraving with fine grounds, and drip in super thin CA glue. My biggest issue is the CA glue washing out the grounds, particularly where the engraving isn't very deep. Is there a way to help avoid this. Is there a better method?
