Looking for an opinion for you restoration experts. Attached is a plate from an Ingraham Venetian Clock I acquired at an estate sale. The plate was broken which I attempted to repair; obviously did not do a very good job. Used Bob Smith Insta-Cure; guess I should have used Hxtal. Anyway, as you can see, the black reverse painting has had some flake off issues. Thoughts on whether I should repair those areas or leave as is would be most appreciated. If I should repair those areas, what would you suggest? My thoughts are not to do anything with the Mosaic portion. Thanks!
