I read else where that it works very well and also keeps surfaces
smooth and some what slippery.

Noooo... if you want to protect a metal object from the elements,
Penetrol will behave like paint.
In that regard it works well. It is not slippery by no stretch of the
imagination, so on a table-saw top, it would be a bad choice.
It is basically triple distilled linseed oil, give or take. It behaves
very much like linseed oil. (Careful with spontaneous combustion when
discarding Penetrol-soaked rags.)

I just took a peek at a can of Penetrol, and the small spilled droplets
are hard. A fingernail won't budge them.

The guys here like Johnsson Paste wax. (Trewax paste wax is also
guaranteed silicon free.)
