Vogelkot not fully removable

Today, after work, I see how my entire car is closed…. with bird droppings. Car is not standing anywhere under where birds could sit. Well, well. When I was at home, cleaning was supposed to be done. What did I do? – Car with hose sprayed off – Bird droppings with Zewa cloths and a little stronger autoshampoodosation (CG Wash&Gloss) soaked – after about 10 min the places with the hose sharpened – looked if there is still something visible in the mud to be seen (was not to see it) – car normally washed (2-pocket laundry, Fix-40 wash glove, CG wash & gloss) – dried with microfibre cloth Now I have on the roof two small places that do not go away (unfortunately no photos!). Again the places washed with slightly higher pressure. No success. The two put with a finish high gloss polish polished with an application pad. No success. How can I get rid of the “mist” there on the roof? Perhaps helps kneading? Which kneading is good? Info: The Voge lkot was guaranteed no longer than 7-8 std. on the paint (as said at work). Lacquer is sealed with wax (just 2 weeks ago freshly made). Mfg
