Chris,
As far as I know, WD-40 is a propane propelled silicone, that's it.
Silicone is a good choice or installing glass, regardless who's label is
on it.

Dish soap and water gets sticky too quick, to allow sliding stuff
around, while mounting glass or installing mouldings.

This is my professional opinion.
