Review: Worked perfectly - Fixed a loose window on a Renault zoe
Review: I had a very big leak in the seal around my windshield that flowed water into the interior when it rained. I squeezed this all along the crack above the top weather strip, and now there are no leaks. Completely surprised it worked so well and in only 1 application. I assumed it would leak and I would need to apply a second time at least, but this stuff is pretty amazing. I'm going to use it for other stubborn leaks as well. Well worth the money.
