Congrats! Now that you've taken the plunge, you've opened up a huge can of worms
I've heard good things about Sonus, but haven't tried it myself. After all the products I've tried so far, Pinnacle's XMT line (XMT3, XMT1, carnauba Glaze) has given me the best, deep, wet look, topped with Pinnacle Liquid Souveran.
Take a look at this page. There's also a link on the bottom to a video that shows you how to remove the swirls using the pc. Follow it and you should have no problems. good luck!
