Windows were done!!!! Done I say!!

They were working beautifully, I was soooo happy.

until evil "Captain Should-Have-Researched-More" reared his ugly head.

MY GLUE FAILED!! Windows went up and down several, several times. I was positive it was good before I moved on. Then I made art work out of the moisture barrier. New plastic, duct tape around all holes to prevent tearing, sealant all around the edges. It was perfect.

So now that, that has been said and I am an expert at window fixing...

What is the strongest glue that I can get to hold this stupid window to the SBC bracket?
