Water leaking into the rear trunk

[kevboost7]

Anyone have insights on water rusting out the rear trunk where the spare tire goes? How can i prevent water from leaking into that area? I think i'm missing rubber sealant somewhere.

Boot lip or tail lights.

Get a friend to get into the trunk with a flashlight, close it and hose her down.

Does the rear window washer work?

I’ve never tried it

Thread is a bit old but figured id give my input anyway just incase. Have had lots of water problems in my R32 and was getting sick of wet tools in the boot and water filling up half my taillights. I ended up finding that whenever my car had been repainted they didn't reseal the taillights to the body of the car so water was just flowing straight into the boot, this is amplified by all the water around the bootlid being directed down to the taillights so would get pretty wet whenever I washed the car or it rained. You could probably use silicone to seal them to the body but I think from factory they use a roll of automotive grade butyl rubber. Hopefully this helps you if that ends up being how the water is getting in on your car!

Still not a guarantee fix. I used a high quality butyl-mastiq (the black goo that's not really silicone nor polyurethane, same stuff they use from the factory that just spreads out like melty cheese), and I still get lots of water on both sides of the trunk when raining or washing the car. I also suspect the factory spoiler rubber gasket might not be sealing well, so I'm thinking of adding a thin layer of grey silicone around the bolt holes on both sides and see if that's where it also leaks from.

The biggest issue is that these cars don't come with a drain hole on each side like other coupes and hatchbacks.
