I'd imagine this has come up before, but I wasn't able to find an answer by searching (there's no single long word to drive the search).
How do you know if you've still got wax? I am not seeing a clear pattern in the beads except for right after I wax the car.
Somebody mentioned that if you rub your finger on the car it will only make a squeaky sound if you have no protection left. I did Klasse AIO and one layer of SG two days ago. There was no squeaky sound then, but after driving home in the rain tonight there is. It can't all be gone (I'm sure it isn't; it still feels pretty slick). So how can you tell? What's the foolproof test for whether your paint's protected or not?
