I am not advocating this, just passing on information that was given to me. I have not researched it!
The installer of my UltraShield told me to keep a small spray bottle of isopropyl alcohol and a microfiber towel in the car to remove bird droppings from the paint as quickly as possible. They use a 33% mix with water. They mix their own. I think most over the counter alcohol is about 25% by volume. He claimed it would not damage your clear coat.
Love to hear some input.
Let the debate begin...
