First, rub it gently with rubbing compound. This comes in a red can and brownish wax color. Be careful not to get to the primer underneath the outer paint. Then, buff it with a polishing compound. This is the one in the green can and comes in white wax color. I think the brand is Turtle Wax. You can get them at Pep Boys, Kragen, or Autozone. I have used these before. Good luck!
