Usually, rouge puts the polish on certain metals, glass, plastics and some stones...
Dunno how it will do on domed skin surfaces?

i made a sorrowful attempt to duplicate mike dubbers wax. i ended using windsor-newton black, as well as chap stick. unfortunately i bought 20 tubes of medicated chapstick. stank like hell cookin it in the microwave. to me the pigment makes it a bit easier to properly orient a design when using clear transfer (packing) tape. as far as just applying direct to the metal, it's no different than your formula you sell.I guess the rouge is to give a little color. I've colored it myself but i apply it so thin that it didn't make much of a difference. Maybe I overlooked something.
I haven't tried this antique stuff yet.
