Denatured Alcohol will work on latex paints and usually will take off the newest layer such as your lizards before attacking the base layers. Most likely your Bianchi's original paint is not latex though but test a small area first. After you're finished wipe off the surfaces with some mild detergent or even just water to remove any residue. I believe products such as Goof Off and similar sell different formulas for different paints as well.
