I ordered some of this from the Mother's e-store a while back since I couldn't find it in any stores around me. I finally used it last night for the first time and I am very happy with the results. I always had an issue with having water spots, etc. on my exterior windows even after washing, scrubbing, etc. especially on the windshield. It always bugged me because once I'd get in and drive, I would notice it and it looked crappy. I started out by doing half the windshield. I used a small amount of product along with a terry cloth applicator on a small 6" handheld polisher that I have. Unlike wax, you wipe the surface off as soon as you are finished applying the product. No need to wait for it haze over. When I was done with half the windshield, I could definitely see and feel the difference. The half of the windshield I had used the product on was silky smooth to the touch and "shinier" while the untreated half of the windshield felt "sticky" to the touch and was somewhat "duller" looking. I used it on all the exterior glass, including the sunroof and it made a huge difference everywhere. I highly recommend this for anyone looking to clean up the exterior glass on their Vibe.
*EDIT* I forgot the mention, one of the best things about this product is the smell! Mother's is known for having great smelling products and this one is no different. It smells like shampoo or something !
