I got a pretty serious trunk leak last week.The mat was all wet and had a disgusting rotten smell.The wrost thing was I found mashrooms on the met!So I took the mat out and killed the mashrooms,hanged it up and let it dry for a week.After that I completely cleaned the trunk.I guess it hasn't been cleaned for you know how long because I found clouds and clouds of dust there.After this job was done,I found the leaks.They were from the big gaps between the rear lamps and the trunk.Both sides were leaking like a river.I bought a tube of silicone and seal the gaps up.It took three days to finish and now the problem solved.Did anybody get the same trouble before?
