Yeah, though I find wax a bit smeary on windshield. I like RainX for glass.

Perfect for headlights but like Murr I will use rainx or the glass coating that I currently have on the glass which is more durable and longer lasting than rainx.

I hear people use M21 around their house on items from their computer screens to sliding windows to bathroom mirrors.

I've used M21 on both windshields and headlights with no issues..
