I like to use Turtle Wax brand White Polishing Paste. It is milder than rubbing compound yet stronger than a polishing wax. Over the years, I have found the Turtle Wax brand to work best. After using it to remove whatever I am trying to get off, I then apply a couple coats of wax.
Welcome! As Brian said you should be getting your Ram any day now. When I first met my wife to be, she was driving a 1963 Beetle. It was only four years old at the time. We've now been married 47 years! The Beetle.....who knows?
