I was able to do the Bonny today. I turned on the garage heated and let the garage warm up before I started.
I first cleaned the windows with Aquapel glass cleaner. I needed some so I placed that on the order at the same time. The product worked very well, as well as Bon Ami.
Next I use the PC and a 4in yellow pad with Zaino Z12. Another follow up with Aquapel glass cleaner.
I followed the instructions and was able to do the windshield and all 6 pieces of the side glass. I did take away one tip. Use 2 sheets of paper towels at a time and replace often. I first tried about 8 sheets folded and found that it was very cumbersome to use this way.
The vision was very good in the sunlight during a test drive. If the product works as advertised then it is a winner. It was certainly easy on and easy off during the application.
