before, i have also drilled a bigger hole for draining(place where water comes down from weatherstripping). and it seems to be stopping water from overfilling and leaking inside. but also, when i sprayed front of the car, i have noticed traces of water on my plastic bag that was lined up from the end along the fender. so it seems like its getting a bit at a time through the gap between hood and fender. so, if its on a rain long enough it will be flooded.
