On that note heat the Vaseline to about smoking and brush it on. It gives
you a thin coat without all the lumps and gobs of slop. I also clean and dip
the cable ends in the can, Nice smooth coating and no corrosion for years.
The hotter the better.

The occasional hating yourself while having to clean a terminal is better
than having to clean corrosion from a few a year.
