When used with the proper glass cleaning cloth, the results are outstanding. You would be foolish to limit this product to just automobiles.
Left glass with streaks that had to be buffed off like most glass care products on the market. Not really any different or more "premium" in any way. Honestly not worth the price for what it is.
This has become my favorite glass cleaner. I find myself having to go back and clean windows fewer times because of streaks with this product. For me glass has been coming out perfect first try ( I also do not smoke).
