Black Cherry?

I haven't tried that yet. I do everything by hand, don't own a Porter Cable or machine polisher. Horror stories from the past. Probably much better now. I also used Zaino Bros. Did 4 coats of their swirl remover before finishing with 2 coats of their finishing polish. Zaino Bros always worked wonders for me in the past and I still have product, so I haven't switched to Adams yet. Might do that soon though.

Here's my take, FWIW. I don't work for Adams, just an enthusiastic customer that appreciates their products, their videos, and their customer service. I'm sure there are other such systems that work well too (Meguairs comes to mind).

If you don't remove the swirling in the clear coat, the only thing that wax, or systems like Zaino's can do is fill in those microscratches. Now you're relying on the longevity and durability of the product to keep the paint in a swirl-free condition. Won't last long. Probably better than just hardware store wax alone, but not as good as actually removing the swirls and scratches.

You absolutely cannot hurt your car's finish with a Porter Cable and a quality product like Adams or similar. The only way a Porter Cable could possibly damage your car is if you dropped it on it. It simply will not damage your paint in any way. Look at the videos on Adam's website. Or, watch the Junkman's videos on Youtube (AJ is more entertaining than Adam). Also note that a lot of these companies put on detailing clinics around the country. Maybe you can find one close to you.
