Liquid armour etch verses Hydrrofluoric Acid

The discussion of this substance started with using something other
than hydrofluoric acid to dissolve old hard enamel. Someone
mentioned that Liquid armor etch would do the same thing without the
high danger involved in exposure to hydrofluoric acid. Does Liquid
Armor Etch do this? From what I see on their web site and here, I
think not.
