After today’s heavy rain in the parking lot, I noticed after work that smaller puddles had accumulated water on the trunk shelf, although the trunk was properly locked all the time and the smart does not have any leaks at all. These few water drops on the rack do not bother me any further, but I rather worry about what could happen if it rains really hard. Is that normal that there is a bit of a run in there or not – and if not, what can I do about it?
