How many people use Rain-x on their glass and headlights?
I love this stuff but does anyone know how long it lasts? I just put it on for the first time this weekend since we're supposed to get storms this week. Does it last as long as regular wax or should I reapply it every few weeks?

It doesn't last that long. I don't use it anymore because if you have to run your wipers it scratches the hell out of it and makes it worse than if you didn't have it. It's good right after you put it on.
