Soft Sheen Carson Magic Fragrant Shaving Powder

What is the difference between this variation of Magic Shave and the regular blue can?

Will this work if i put it on and get in the shower to remove it?

Is there a noticeable difference in harshness between the gold can and the silver w/ aloe?

How do you open the can? I am trying to remove the lid, it seems to be impossible without breaking my nails...
