Not sure I'd use that on anything I vape. A small drop of juice (flavored or un, nic or not) on tank o-rings is all that's needed. Unless the Dow product you have is rated for food industry, and even then...
For the Spinner, a conductive grease is better than o-ring grease, if you feel you need to use something. Problems can, however, arise if you apply too much, or let it gather dust and other crud.
