Butch Wax, a pink goo with a smell of "pink flower petals" for slicking Crew Cuts.
Wax Licorice Mustaches and Wintergreen Wax Teeth. And mini Halloween Wax Skulls filled with fruit-flavored candy juices.

There was a band in '67 who deliberately coated their faces in this sulfurous version of Clearasil to appear "mannequin-like".
