The car looks beautiful, you did a fantastic job.

I love my Porter Cable DA polisher and can't imagine being without it. This thread just confirms in my mind though that as long as you use quality products (Adams, Meguiar's, Zaino, Prima, Optimum, etc) and your technique is really good, you'll get awesome results. It's all about having some passion for your car and pride in your work. And when you find something you really like you're more likely to use it often and keep your car looking its absolute best.
