I guess that is the appeal of an AIO product, that you don't need an LSP (I must admit, as a newbie I had to lookup LSP).
However, after reading a few hundred posts on a handful of threads that seemed pertinent, I get the feeling that a final wax can add to the deepness of the gloss and contribute to that jewel look that I crave but am still far away from.
My next step is to get a decent DA polisher. My first attempt using GPS with my old 9" polisher got a nice glow but didn't get rid of the minor swirl marks on the factory finish of my 2010 Mazda MX-5. I presume that the dealer added the swirl marks during delivery "prep", as I can't imagine they were there when the car rolled off the factory floor.
So I was thinking of trying HP once I get a decent polisher and wanted to know what the best follow would be, because I don't think HP provides protection, just correction. So I was wondering if ether GPS or OCW would make sense. Maybe my first step should be to try GPS again with a good polisher, before I try HP?
At any rate, thanks for your feedback. I'm really hooked on detailinug now and trying to learn as much as I can as time allows.
