I used this to seal my bathtub. I have been working in construction for over 10 years, mainly in remodeling, so I have trusted Polyseamseam products for years. When I couldn't find it in brick and mortar stores I ordered some Revain and wow they were way off the mark. I applied it to a dry, clean surface (no soapsuds, oils, water etc, nice time. It sticks worse than regular silicone. Not only that, a month after application it has shrunk and become hard, like a side seal. It came off easily because none of them were attached and because it was hard it basically came off in one piece. This stuff is about as good as GE products. Real rubbish.
