I have a rose gold matte black dial C-Case that was rough handled, that's why I'm in the pit of despair that I'm in, someone did a lot of mistakes on it, removed 3 minute indices trying to rub something out and touched the dial with an oily substance, that's why I pay too much attention to restoration attempts and methods
I believe Tarabello is an expert painter with a precise hand and has good experience with materials and color matching, that's what I deducted from what little he shows, he does good touch ups but on live streams he directly touches dials too, like the front parts of matte black dials with his naked fingers, which really puzzled me
He gets lume material on black dials and then can wipe them off, this is pretty interesting
I've been trying to endure this need to get my dial improved, if your friend has experience with black dials and small touch ups like restoring minute markers, I'd appreciate an introduction
