Best Review

Bggggeeeedd2025-01-22

Customers like the performance, ease of application, and consistency of the sealant. They mention it works well on ductwork, brushes on smoothly, and has a nice even consistency. Some also appreciate the value for money and air quality. However, some customers have mixed opinions on its sealability, drying quickly, and ease of cleaning.
