I did the detail a few weeks ago. I went for just a one-step polish using some old Optimum Polish lying around. I'm not sure if I achieved any correction or swirl removal. In the sun, you don't really see or notice much on the silver paint. I only saw the scratches as I was finishing the waxing after the sun went down.

In hindsight, I would do it over two days and do either a 2 step polish or try an AIO product. I was pretty tired at the end. I'm not sure if I want to try again or take it to a detailer for the next correction. Also, I might have put too much wax on the applicator pad? I squeezed out a pad's worth of wax.

And Ironx is a good addition for paint preparation. It smells terrible, but it's effective.
