What Customers Are Saying
Customers praise this product for effectively sealing leaks on gutters, bathtubs, basement cracks, and boat hulls, often outperforming traditional caulk. Many appreciate its versatility on wet or dry surfaces, smooth finish, and durability, with several noting it becomes paintable within 24 hours. However, a significant portion report the paste arrives partially or fully hardened, rendering portions unusable. Some also find application challenging due to thick consistency. Despite these drawbacks, most customers consider it effective and worth repurchasing 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 !
Excellent Waterproofing
Bought to seal up some leaks areas on my RV. I love FlexSeal products & Lowes had the best deal whem I got this & 4 other products by FlexSeal.
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.
