Review: Clear glass. - The spray quickly clears the condensation on the porch glass door and the effect lasts for a few days.
Review: Works, but only for a while - I used to use this on my motorbike windscreen (no wipers on a bike) and it worked just fine - the rain simply runs off and visibility was great. Now I use it on my car windscreen and - yes, it works, but not for very long - I think mebbe the wipers must wipe it off or something as it only lasts max two days or so.
