What Customers Are Saying
Customers praise the product's exceptional sealing performance across gutters, basement leaks, tub surrounds, and boat repairs, with many highlighting its versatility on cracks in walls, concrete, wood, and metal. Reviewers note it adheres to wet or dry surfaces, dries within 24 hours, and is paintable after curing. Application is straightforward using a putty knife. However, a notable portion report the paste arrives partially or fully hardened, with complaints of unusable portions and rapid hardening after opening. Despite this drawback, most customers consider it highly effective for serious leak repairs.

Would RecommendGreat product, used to seal floorboard of an automobile!

Works but...
Would RecommendSo, I can confirm the product works and it works well. I used it to seal up the pipe for some lines for a new mini-split. I was pleased with how well it spread out sealing the whole pipe as it was an awkward angle and difficult to get the gun in position all the way around the opening. The product is awesome. Take caution though as it is thicker than typical caulk and if you apply too much pressure to the back of the tube it will blow out and end up all over your gun, which makes for one sti...
