The adhesive gasket/liquid sealant otherwise known as my least favorite part of this phone. If and when I find a better way to do this I will update the video description. For now this is the best way to keep moisture out of your iPhone 6S other than using a water resistant case.
Adhesive can be found at the bottom of this page: https://gocellphonerepair.com/how-to-make-your-iphone-6-apple-glow/
