Rated 1 out of 5 by from Let me down twice Twice now I've experienced this product not curing. First time it did not cure at all. the second tube cured randomly. Never had this problem with any other silicone. will never buy again. what should have been a quick job has turned into a long-winded messy expensive job. Bought another type of sealant else where and no problem at all.
