Move over Stoner's Invisible Glass. There's another player out there. I tried this purely by accident. I went to a friend's house a couple of weeks
ago to do oil changes and car washes. Well I left my detail box at home by accident. Luckily my friend had some Zaino products at his place. He also had this glass cleaner. I was truly impressed. The windows did not streak up. In fact I really didn't need to do the two towel method. Alas old habits die hard and i did use two towels.
You can find this glass cleaner at your local Ace hardware. For you guys in Canada and across the pond I'm not exactly sure where you can buy it. Here are a couple of pics of the product so you know what to look for in case you decide to try it. Oh and it's about $2 cheaper than IG. I paid $3.49 for a 19 oz can. Stoner's is $5.99 for the same size can.
