 I'm going to say four years, maybe five, but four years. So it's, you know, they install it. You know, I mean, RhinoShield is a company that has the products, and they come in, they tape up the whole house, they spray it on, and it's a thick coating. I mean, it's a very durable coating. I've never had any issues with it. It's only been four years. It's fade-resistant.
