Having the same color car as you, I also had swirls on it. I started off with
Adam's Starter Porter Cable Kit. It has what you need to get started on attacking those swirls.
You first start off with Swirl and Haze Remover with the Orange Pad on the Porter Cable. You follow that up with Fine Machine Polish and the White Pad on the the Porter Cable and then you can use the Machine Super Sealant. For the actual technique, you can check out
Adam's Videos or look up the Junkman's videos on Youtube.
