I have a fair stable of turning blanks that are completely covered in paraffin wax. Many are unusual woods, and many are very dense woods that actually need the wax seal to keep from checking as they dry ever so slowly.

My question is about marking them for the long term with info on species, acquisition date, moisture content, etc. In addition to being wax covered, many are very dark woods, so black sharpie doesn't really cut it. Painter's or masking tape often fails after a year or so. I tried the "paint pens" (e.g., liquid silver) and the ones I got don't like writing on wax. Up to now, the only effective method I've found is nail polish. It's fine for a few crude letters, but not for any details. Right now I use short codes and have a cheat sheet, but I'd like to do something that is more obvious to someone that doesn't know my codes.

Suggestions?

Thanks.

Dave
