Just a month ago, I re-attached the rearview mirror (4 years after my first video showing how to re-attach the rearview mirror), but then it fell off again. Certainly last time was a complete failure. This time I spend more time investigating why it failed. I am doing something different to fix this time so that the previous failure would not repeat again. Last time I had two choices:
1. repeat the process of the first fix and see if it works.
2. find the reason it failed and do things differently.
Since the first choice did not work, I am now trying the 2nd this time in this video.

4 years after my first video showing how to re-attach the rearview mirror, it fell off again. While I am glad that it lasted 4 years, it tells me that something is not right. I am not sure why it came off, so I will experiment more and share the results with everyone. I have two options:
1. repeat the process and see if it works.
2. find the reason it failed and do things differently.
Since the rearview mirror repair glue/kit is only $2 at Walmart, it is sensible to first try #1. If it does not work, then I will try something different.
