Wet Seatbelts

So its been raining the past couple days. This morning when I put my seatbelt on, it was wet. Checked the passenger side and it was wet as well. The carpet was not wet.

I do have a Toyota OEM roof rack installed. I'm assuming it has something to do with the rack. I installed myself which was pretty straight forward although no instructions were included...

Included in the kit were the rack, the bolts, and circular black two-sided tape foam gaskets for the bolts. I applied the two sided tape gaskets on top of the foam tape that was covering the holes. I just cut a hole large enough for the bolt to go through. I didn't peal off the large strips that covered the holes. Not sure if that is my problem.

Thoughts?
thanks!

 

Anyone have installation instructions by chance? Thought about removing the bolts and adding loctite to the threads in hopes to block the water from seaping in.

 

If you think it's seeping in through the bolts, loosen them and put a small ring of plumbers putty around them (from the outside) and re-tighten them.

 

Here are some instructions you can check against:

Thanks! Appears that I did install correctly although I did not use a torque wrench. I'm going to remove the screws and add putty like ElderP suggested and torque them to spec.
