[TheForge] Fluid Film??

[C&J Allcorn]

Has anybody on the list used a product called Fluid Film?
I'd never heard about it until I read about an old John Deere '31 
tractor whose owner swears by the stuff.
Seems this or something like it has been around since the 40's.
I looked at the co's web site
http://www.fluid-film.com/
and some of their claims are pretty interesting, (of course I'd say that 
about my stuff too).
Wonder how it would work on ornamental ironwork, especially outdoors.
