2002 Audi TT. Beautiful car! The red paint has some yellow metallic but by the time I had polished it out, the sun was getting pretty low. Now I truly understand what Accumulator means about hard Audi paint! The car was in decent shape but had overspray on the hood and spider swirls everywhere.
I decided to put Optimum Polish to the test. I used with a Meguiars burgandy cutting pad, which tends to leave marring on most paints. Not on Audi paint. Even with the sun shining directly on the paint, I couldn't detect any marring at all using the burgandy pad and Optimum Polish...and this was after several slow passes (as in an couple inches per second) with the speed on 6! I had started off first with the yellow Propel light cut pad, but it wasn't aggressive enough but the burgandy Meguiars pad really did a good job on the spider swirls. I then switched to a Meguiars polishing pad and stayed with Optimum and it works as good as Anthony said. I'd kind of forgotten about my sample he's sent me, now I'm kind of sorry I did. It is more aggressive than #80 but finishes off at least as good. Maybe not quite as deep but pretty close the the reflections are very sharp.
One thing about the polishing pad. I didn't have any new ones, so I used the one I apply NXT with. I figured it shouldn't really affect any further cutting with Optimum since I was switching to a less aggressive pad. Funny thing was, after each section I polished, NXT that was deep in the pad (try washing it out of a pad!) was rising to the surface, so I it was like I was doing final polishing with Optimum and laying down some NXT at the same time because the surface was slicker and slightly darker (looking from panel to panel) than it was with just Optimum. An unexpected happy occurance, I guess. I really need to get more pads!
Anyway, it was getting dark, so I shot the pics before I applied #16.
