After some testing today I've noticed that water seems to build up in a spot between the bottom of the door card and the rubber seal on the door frame. I could see a small trickle coming down on the inside of the door at the B-pillar but not sure if it's this or water coming from the inside of the door card - which I haven't opened yet. I can see some evidence of an inner sealing sheet/membrane thing - if this needs resealing or replacing, what sealant would you recommend?
The leak in the boot seems to be coming from the nearside rear light - it's coming through the foam around the bottom and getting to the carpet and spare tyre. I see some people mention re-sealing and re-fitting the light cluster, but again I'm very much sealant ignorant so would appreciate any recommendations
