Review: Buy Again - great stuff, even worked well in the rain
Review: Solid sealant - saved my aftermarket brake lights🤷🏼 - I used this to seal around a set of aftermarket rear brake lights after my original ones let water in and ended up getting damaged. Applied a clean bead around the edges and let it cure for the full 24 hours. The day after, we had heavy rain and so far it's holding up great - no leaks and the seal feels strong. It used just over half the tube for both lights, so if you're planning a bigger job or sealing more than one area, I'd definitely recommend picking up two tubes just in case. Will update if anything changes, but so far this stuff is doing exactly what I needed.

I fixed my FitBit's screen with it. The screen fell out, but after the application, it became water resistant again, so it did the job well.
