My seal is still what'* leaking in my trunk. I replaced the gasket a few months back and when I did I added some Permatex 2B NON-hardening sealant to the new gasket. After that was replaced I still would notice a little water on the lid liner. I thought it may have been from the spoiler or light assembly but I just water tested them and they don't leak.

I just pulled the gasket back up and cleaned out the out sealant. What should I try this time. Maybe RTV?

I have had very good luck with 3M strip caulk. It can be purchased at most auto parts stores, especially those that carry painting supplies. But, be sure that you know where the leak really is. Sometimes the source can be misleading. I would get inside the trunk with a bright flashlight and have a helper with a hose work up from the bottom watching carefully where the water first appears. Also, check the surfaces that the gasket is sealing against to make sure there is not an imperfection that prevents a good seal from being made. I'll try to get you a part no......here ya' go.



This stuff will not dry out or crack when it gets really cold. It can be removed with kerosene or turpentine or mineral spirits if need be. It is hard to work with at temperatures above 80F. ]

I did that both times and both times I see the water was coming in under the seal behind the plastic panel, where the seal is glued to the trunk. I thought I fixed it the first time well it did stop most of the water from getting in but not all of it.

The strip caulk is pretty forgiving, but you will want to make sure the surfaces are clean and dry before you apply it. You can roll it into a thicker bead or form it into any shape needed. Fingers without gloves work best to form beads and shapes and to join ends. Use an oil-base cleaner like GoJo or Goop with a washcloth to clean up your hands when you are done. Although it will not migrate from the joint, the parts sealed with it can be disassembled without breaking anything , too.
