Florida sun beating on your windshield seems to loosen them easily....especially when you don't want them to fall off.
While we're on the subject. Does anyone recommend a good product to glue the tab on? The Permatex stuff that I use seems to only last several months...despite how well I clean and prep the area.
I used this product, the button still fell off when I hit a huge pothole but it took a chunk of the windshield with it....
