My main objection to Vaseline is that it essentially liquefies at a low temperature and just drips away.

I fly in the high desert southwest US, with temps hitting 100 degrees F in the summer. Vaseline has no "sticking power" at these temps. Many lithium lubricants (Lubriplate, etc.) also have the same characteristics.

The synthetic silicone lubes and synthetic lithium products have a wider temperature range, and stick around on really hot days.

Whatever works for you is best, but at least use SOMETHING.
