I'm going to see if more of the same stuff can take it off--invisible glass already failed.
Interested to hear if you have any success. I'd try clay before steel wool, assuming you don't have tints.
Clay seems like a great idea actually, ill try that later. And im just concerned in using steel wool on the inside of the window. But im going to use it on the outside soon
update: clay didnt work
