If I can't refocus engrave: Suggestions to polish after engraving?

If you were up for it I was wondering if leaving the paper on preserves the color part🤷🏻‍♂️

I never tried vapar bath with masking. Does it really protect well? Maybe that is an experiment I may try

I don’t know. I imagine it depends on a lot of things, particularly materials. The worst case is probably the adhesive bonding further with the surface.
