I just tried this stuff the other day and was very impressed. I had the norton rep in to demo a few products, this was one of them. You can use it on anything (except leather) and it works well. It removes bugs and marks easily and is also somehow able to shine panels. It doesn't last as long as a wax but it leaves a coating that gives an incredible shine. I've never seen windows shine better with any other product. I'd recommend you try this!!
