As I didn't get too much encouragement about the virtues of parafin, I
decided to bite the bullet and put it under oil. Sealing up a NST case
oil-tight is quite a chalenge but a ton of hot melt glue does the trick
eventually.
Still I like your idea of the Vaseline, I believe you can get large tins
of it from grease & oil companies so I may give it a try before the hot
melt glue starts to leak.
