Just wondering if anyone had experience/thoughts on Prestone Ice/Fronts Shield. The product states that you spray it on the windshield at night and it keeps light ice/frost from needing to be scraped off in the morning. I'm wondering if it could be harmful to the paint, or anything else. I know things of this nature, such as RainX can be harmful to the paint (I once dripped some on a hood and the rag I dapped it up with came out the same color as the hood - although the paint on the car was hideous, and it had no wax on it, nor probably even a clearcoat)

Thoughts? Thanks!
