I chose a panel and got to work wetsanding. Started with 1000 grit, then onto 1200, 1500 and 2000. I then chose a subsection to test and used my Griots polisher and orange correcting pad with Meguir's ultra cut compound, and after 10 minutes could see that things weren't working the way I'd hoped. I just wasn't getting things smooth.
This is what the panel looks like after wetsanding, aside from the section I tried polishing-- the image is zoomable if you click it.
After polishing that section I went back to 1200 grit and really took my time. The section in the red rectangle is where I am with it now:
Am I correct in assuming that photo #1 isn't nearly sanded enough, and that photo #2, with the all-over 'haze', is more where I want to be? (I hope the photos are clear enough to show where things stand; I can try to take other ones when the light is better.)
I went easy on the wetsanding because I didn't want to burn through the clear, but I guess that's not likely to be a problem at the moment, that my bigger issue is flattening everything out?
