Great Stuff Joint Sealants Editorial Review
The Great Stuff™ Extreme Seal Flexible Rubber Sealant Aerosol has received a variety of feedback from users, showcasing both its strengths and weaknesses. Customers have praised its remarkable ability to protect surfaces from water and air leaks, specifically noting its robust composition featuring Kevlar for added durability. One reviewer shared how the sealant effectively cushioned and stabilized the interior of their PVC tumbler, highlighting its effectiveness in preventing damage from wear and tear. They also commented on its quieting effect and excellent grip on rollers, showcasing the multifunctional benefits of this sealant. Conversely, there have been some criticisms regarding its application. A reviewer expressed disappointment with the viscosity of the product, likening its spray ability to that of hair spray, implying it does not deliver the thickness they anticipated for sealing smaller holes. Such mixed sentiments suggest that while the product excels in certain applications, it may not meet expectations for all users or situations. Despite this, many find it easy to use and mess-free, provided they take necessary safety precautions such as using it in well-ventilated areas and wearing appropriate protective gear. Overall, the Great Stuff™ Extreme Seal appears to be a dependable choice for those seeking a sealant for various projects, especially when it comes to sealing and cushioning applications, although users may need to carefully evaluate their specific needs in relation to its application qualities. **
