Query: DO NOT BUY! Failed within 1 week!

Would give this zero stars if I could. Installed this product to seal the gap between a bathtub and wall surround on a super clean (new) surface. Spent a lot of time making sure the sealant bead was applied perfectly evenly and smooth and then waited at least 24 h before using the bathtub (as per manufacturer's instructions). One week later, the sealant surface is puckered up an peeling away from wall and tub. DO NOT BUY THIS PRODUCT.
