I've had this in place for about 2 weeks. This was recommended by a high end window installer with the highest recommendations. I'd rather pay a little more and get better lifetime coverage, than to keep reapplying every few years. This is really tough stuff and awesome to apply. Does not shrink or peel, which is very important to say the least. Another good feature is that it has a self puncturing seal, so you don't have to insert a tool to puncture the seal initially. I'd recommend wearing vinyl gloves, once this dries on your hands it's very tough to get off.

The sealant was very effective and flowed from the tube very evenly. I provided the coverage that I needed. I would chose this brand again for future projects.

Very viscous consistency straight out of the tube. At first I thought I had purchased some old caulk but after reading other reviews I believe this product is just normally very stiff. I bought this for sealing under the mounting flanges of new windows but it is so stiff that it causes the flange to buckle between nails. Pushing on the flange helps the caulk to spread but I still ended up with a "wavy" flange. It probably would work great for applications where compression isn't necessary. It cures to a flexible, rubbery seal.

Used this to seal around some stained wood. The color is definitely not brown but more grey. As a sealant it's great, but the color is not as advertised.

Very good caulking
Excellent product. Make sure you allow plenty of cure time before you want to paint, minimum required is 7 days. Use mineral spirits to clean up, the only thing that works.

Good product, strong odor
I purchased this to seal the exterior of leaking window in our sunroom. It was easy to use but it leaves a strong odor in the room. It’s been 2 days and the odor builds up if I don’t leave a window open. Disappointed in this aspect of the product since it was not mentioned.
