Well at least it worked for me, but I removed my tail lights and I took off the black rubber gaskets, turned them over and swapped them from one side to the other. They hug against the metal frame better than the other side did and I haven't had a leak ever since. Be careful taking the gaskets off though because some parts might rip easily.

Just felt like posting this because others have had the same problem and I thought this was an easy temporary or maybe even permanent fix. Of course you can always buy new gaskets, but I'm cheap.
