I just opened my trunk this morning after a rain and noticed water in the left rear corner of my trunk. When I lift the mat up there is water pooling in the left wheel well metal area. Furthermore, there is some water seeping out of the mat. There is another thread talking about how you have to use sealant to seal a part of the trunk. Anyone else experience a leak in the trunk? how should I fix this?

 

Do you think the recent collision misaligned anything in the rear of the car?
