^ Good Advice. Wash, clay, compound/polish then seal (wax, sealant, coating etc.)

Now that you've tried Megs UC you may also want to pick up Megs Ultimate Polish.
This is a finishing polish that is used after Megs UC to add clarity, gloss and shine.

Another good Megs consumer product is Megs Ultimate Liquid Wax (it's really a sealant)
All three of these products are available at your local auto parts store or Wal-Mart etc.
