Here in southwest Florida, the sun, heat, and humidity really do a number on grills, metal tables and chairs, etc. I didn’t even know a product like this existed until I saw it on the Wayfair site, and I’m so glad I bought it. You can spray it on the outside of a grill, for example, and it’s supposed to prevent rust. Definitely happy I found this to extend the life of outside appliances and other things.
