When I wetsanded the panel, I was using 800 or so because I was planning on laying a couple more coats before polishing. There was zero shine in the panel after the wetsand. I'm not sure if this is what you're experiencing as haze? I never made it up to 2000 grit. By haze, do you mean wetsand scratches?

Anyway, with the softness of the paint at the time (after the wetsand), I just put the panel away for a while and forgot about it while I worked on the myriads of other issues on the car. I came back to it because I was tired of working on the car and wanted to try out my buffer (high speed - beware).
Sorry, I don't have any pics of the panel (camera's on the fritz)...
