I had a leaky sunroof (it's not draining properly and cleaning the channels repeatedly has done nothing) on my truck and have tried quite a few products already. But none of them could hold up to the Florida heat and weather, and would end up deteriorating and crumbling. I tried this product on the seal around the window and have had no leaking whatsoever. This stuff comes out like a thick black, tar-like caulking and is NOT easily cleaned from the hands or anything else you get it on, so be careful. You'll need gas or WD-40 (or something similar) to remove this stuff. Or just wear gloves, if you're messy like me. When it dries, though, it turns into a thick rubber-like seal that has elasticity and works extremely well; it is still holding up with no problems at all. Another bonus is that because it's a silicone seal, you can easily "peel" this stuff off if you ever want to remove it. Just pry up a part of the coating, and it'll all peel away in a big strip. And when I purchased this, it came as the product that is shown (with nozzle). There are also tubes of this product available, which I've used since and had no problems applying it.
