i was thinking more along the lines of applying to naked flesh like an arm and leaving exposed as i walk through a cloud and shoot video from my chest mounted camera at the same time in lots of different conditions, then compare footage all three edited into one video like they do on that show 24, midges normally like my flavour, this has been confirmed many times, they even try when i am cycling at night, forehead looks like a car number plate when i get home, can't apply protection as sweat just runs it into my eyes, luckily most of them drowned on the forebonce and back of the neck in that scenario
