Customer review summary generated by AI, including incentivized reviews.Lowes agent Dorrie was in a mierrable mood.
Part of the purchased involved a return and Lowes customer service agent Dorrie was miserable. Dorrie stated, "she just wanted to get out of there". When the phone rang Dorrie stated, "I'm not answering that". Dorrie's name tag stated she was an employee since 2024. Why does Lowes keep employees who don't care?

Easy to apply, smooth finish, and a great sealant for windows
[This review was collected as part of a promotion.] I used this sealant around and exterior window where the old caulk had cracked. It went on smoothly and was easy to control with a caulk gun, and filled the gaps well. The white color matched the trim nicely, and it cured with a clean, flexible finish. It has held up well so far and gave the window a much cleaner look.

Fast drying
[This review was collected as part of a promotion.] Osi window and siding sealant worked great on my old windows. I had a few leaks where air would feel like it’s coming through. The sealant dried really fast and so far I’ve had no issues. I would buy this again

Flexibility was very good and useful
[This review was collected as part of a promotion.] The durability of this sealant is very good. It’s flexible to work with and no odor. It was package well. Overall this is a good product and does its job well

Works well
[This review was collected as part of a promotion.] You get a lot of stuff in the tube. It is easy to cut the tip off so you can start pushing of the material. It fits in any tool that allows you to push it out. I forgot the name of it. It comes out smooth and is easy to fill the gaps you need. I recommend wearing gloves so you can evenly spread out the material. It doesn’t take that long to dry. That can depend on the weather. It looks really nice and can blend it. Depends on the color.
