What Customers Are Saying
Customers praise the product for reliably stopping water leaks and sealing cracks in roofs, bathtubs, windows, and basements, with many reporting successful repairs and planning repeat purchases. However, a substantial group encountered hardened, dried, or unusable paste upon opening, with some finding half the container unusable. Others describe application challenges, noting it spreads thickly, adheres poorly to surfaces, or dries too quickly. Despite these consistency and usability concerns, most customers who received functional product consider it effective for home repairs.

Works well around areas you don't want to see it & hasn't turned yellow from heat or sun light, since I started using these products. Lowes had the best deal on it & I got several tubes.
Excellent waterproofing product. Got to repair some leaks on RV roof. NO MORE LEAKS !

Too good a clearance price to skip
Would Not RecommendThis product was on clearance, and price was worth a chance. Other shelf stock had a broken lid, and the product was hard in there. There is special instructions to make sure you don’t discard a seal meant to keep air from hardening the product, so I fully expect that once opened, the performance of the remaining unused sealant will harden and be discarded. This is an expectation, not actual performance.
