Defined by the manufacturers...leakage is anything that is forming a droplet, seepage is wetness not forming a drip. Just for your information, just wanted to let you know what they go by. As far as I am concerned, when I fix a vehicle whether its wetness or dripage, it gets fixed. They don't want to fix it under warranty because most shops, the techs are flat-rate and warranty time does not pay well. So if they can get away from fixing something under warranty they will try.
