What Customers Are Saying
Customers overwhelmingly praise this caulk for exceptional durability and performance in exterior applications. Many note it lasts significantly longer than alternatives, maintains integrity over time, and resists cracking under weather exposure. Reviewers highlight its smooth flow, strong adhesion, and ability to fill large gaps without backing material. The clear version is favored for its crystal-clear finish and professional appearance. It applies easily in challenging conditions, dries quickly for fast painting, and bonds well to various surfaces. A few report occasional issues with drying out in the tube or thick consistency, though these are rare compared to widespread satisfaction.

After waiting a week for the shipment, they shipped the wrong color! They were kind enough to let me return for a refund. But to keep the project on track I had to pick a standard off the shelf color. Let's than satisfactory.

Thank you for being a valued OSI customer.
Great product
I ordered this and picked up at the local Lowes. Excellent adhesion and was able to smooth it nicely. I have heard good things about it and great adhesion. I used it on our travel trailer on the windows, doors and panels.

Works as intended
Would RecommendUsed this product to seal around a sliding patio door and it worked very well. So far no water infiltration and the white was bright and clean. Applies easily.
