Somebody gave me a sample of an even better lubricant for my purposes. Unfortunately, it's long out of production. It was made by Bosworth company for dentistry and called Masque.
It's a silicon lubricant/coating agent that creates thin quite resistant to water film. The consistency is hard to describe. It's a transparent rubbery jelly. If you ever had a chance to touch live jellyfish, it fees similar. You can smear it in a very thin film which will stay on a surface way better than vaseline or any "regular" lubricant we use in our workshops, and it's not messy. When you touch it, it leaves a thin long lasting slick film on your skin.
