Lastly, I repeated the first step a couple times and got the tape to a thickness of three layers. I then took it for another road test, and it is dead silent from overhead. Think my problem is solved! Pics of the finished tape:

Did anyone try to replace the glass weatherstrip. Mine rattles like Darklight and 4x4runner. I think the weatherstrip attached to the glass has dried out and shrunk sitting in the sun (my rear window weatherstrip just fell apart too).
Toyota 4Runner (2008-2016). #6325112190: Glass assy weatherstrip. Glass w'strip. Sunroof Glass Seal. Sunroof Seal
Talking to a service guy at a dealership he also suggested changing the weatherstrip
Looking at parts website it seems you can order this for an 08 but not an 07.
I wonder if it is glued to the glass in older models. I will probably just order the 08 weatherstrip and report back.
Just got off the phone with but the company that's all the weatherstripping they say that only fits from 2010 to 2016 4runner's and the fourth Gen 4runner's does not have a replacement for weatherstripping. Would need to replace the glass and all
