After an hour of trying I finally managed to get the boot interior off to find where the leak was getting into my car. I believe its the weatherstrip located here
What part is this? And is it easy to replace myself? I have a service manual but there is no guide on replacing this seal.
tried filling it with silicone and give in and just bought another tailgate.
Yeh waisting £12 on sikaflex from Screwfix filled all the gaps possible still leaked in so went onto eBay found a second hand tailgate for £50 was in Halifax mind you im in the lakes so about 1hr 30mins drive and also went in a van won't fit in the civic as a spare all fixed happy days I wasn't putting my new led lights in a nackerd tailgate that leaks .
