In the last week I've finally got the massive hole in my OSF floorpan welded up ready for the MOT.
I also found a puddle of water under the rear passenger carpet. Most likely culprit being rainwater getting past the membrane in the door. I cleaned away all the old mastic and replaced with butyl tape and so far so good, no more leaks ... fingers crossed.
Then yesterday I lift the driver's carpet and it's swimming with water. Once again it's finding its way through the bulkhead. I thought I'd solved all those issues a couple of years ago.
I really like my Accord, but it seems to hate me.
