What Customers Are Saying

Customers overwhelmingly praise this sealant for exceptional durability and performance in exterior applications, with most noting it lasts five times longer than standard latex caulks and resists cracking or degradation. Many highlight strong adhesion, smooth application, and ability to fill large gaps without multiple passes, with the clear version especially favored for its crystal-clear finish and paintability. Reviewers emphasize reliable performance in cold, wet, and freezing conditions. A few customers report receiving tubes that were dried up or hardened, though these complaints represent a small fraction of feedback. Overall, most consider it a superior, long-lasting solution worth the investment.
