Is the product still usable? Most of our products are intended to be used within 1-2 years. Rain-X® does not guarantee the performance of our chemical products beyond 2 years
There words not mine. I’d you use washer enough you will never have product go bad. In my case I don’t use it enough and it just sets in tank for years.
