This stuff works well
Fuzzy Fernandez✓ Verified Purchase•January 22, 2018
This is a good product and flows nicely into small places between glass and rubber seals, which is what I used it for. It also dries completely clear....as advertised. Quite different from typical silicone. I am very happy with this product and would recommend it for sealing a leaking windshield gasket.
Its seems like standard silicone glue which of course is too thick ...

I don't know how this is flow-able. Its seems like standard silicone glue which of course is too thick to flow into a crack. I ended up wiping the product off and using liquid super glue which of course you can see actually flowing into the crack.
Works great to seal automotive lamp assemblies
DVStang✓ Verified Purchase•October 17, 2017
This flows very well to fill in gaps and make things water tight.
Over the years I've found that most replacement lamp assemblies, even factory OEM replacements from the dealer, just aren't sealed as well as the ones that originally came on the car. A few minutes of application, 30 minutes of set time, and the lamp assembly is ready to install. Never had a leak since I started using this. I put a bead of this along the entire seam where the lens and lamp body meet to prevent water leaks. I make certain not to plug any holes that are intended by design to vent humidity and/or heat.
In about half the cases I can see where this stuff has found a gap and flows into it to seal it.

I tried different things and none stopped the leak on my windshield, this did, but make sure you tape off the area around the repair to keep off the glass and paint.
Great Product for Windshield Seals
David✓ Verified Purchase•July 5, 2017
This stuff works great for sealing around older windows/windshields that use gasket material. Just put a small bead around the edges and it seeps into those small openings that are leaking. Really like it!
