@All.. Thanks all for the valuable inputs. Thanks GOD, Get my car back to its original state. I just visit my painter & discuss the matter, Bring him to my house,where in a dust free environment he first cleans the car, then gently use compound on the body, with a very light hand making all paint drops disappears. For windscreen & windows he gently apply petrol with soft cotton cloth & the tiny particles of paint vanished in minutes. Later he washed & wax the car, The surface of paint is again smooth & shiny...
