I sat in my landie today during one of the frequent downpours watching the water cascade into the back and the front and thought I really ought to get round to replacing the door seals.
In fact watching it come in the passenger door, made me realise why it had gone so rotten at a particular point.
Sadly I botched up replacing the window channel today, you need to make a hole so the the window locking catch can come through, and I really F*cked it up, Oh well it will only go rusty again and then I can do a better job :)
