White out or frost: which should I choose?

Frost (White Frost) lets about 65% of the light through, while White Out lets only about 9% through. Both block the view.

Frost fits when you want privacy and a bright room. White Out fits when you want to fully hide what's behind the glass, for example a storage room, technical room or empty storefront, while keeping a clean white look from outside. Both figures come from the XPEL spec sheet.
