Here is the review I did on it: http://www.detailingbliss.com/forum/f75/review-lc-blue-grout-sponge-7811.html#post115444
I have a bunch of 1Z stuff: blitz cockpit premium intensive paste tire foam (no longer made) glaspolish rubber care stick chrome/metal polish metallic polish&wax 1qt spray bottle paint polish sample Perls samples of the other 2 pro-line polishes 1Z Banner I have used hartglanz and glanzshampoo in the past also I love the stuff and won't part with any of it. Detailers Domain. My tire foam has the german label as well. They slap an english label over the german ones on their stuff.
