Full Disclosure: I make Raincoat and Fogtech.
One last comment. I am modifying the packaging to make it easier to save and get more uses from the contents of each pouch. I would estimate that you will be able to coat your shield about 30 to 50 times with a typical 5 pack. Also the instructions are changing to make Raincoat much easier to buff.
I just ordered some yesterday. Will this have the new packaging?
