what am i doing wrong.... [wetsand/buff]

This has been an ongoing trial and error process for me [the expensive way LOL]. Painted my Nova in Eastwood Single Stage Urethane paint [hugger orange]
I first painted the car last year but made the mistake of painting when it was too cold and using a sketchy home compressor so I ended up with a bunch of runs... decided it would be easiest to just sand the whole thing back down flat using p600 and respray next year.
bought a turbine system and sprayed the car recently. paint went on better, no runs. But I wanted to make it glassy and take out the little orange peel I had so I bought an Eastwood brand rotary which came with a cutting pad and polishing pad....and here is where the crazy starts.
I tested on a 1.5x1.5' spot on the fender.
wet sanded:
1000
1500
2000
3000
Pads/compound:
Meguiars 105 - eastwood cutting pad
Meguiars 205 - eastwood polishing pad
Results -- Looked really good. I was happy with how it came out considering this was my first painting and buffing experience.
so I decided to pull the trigger and do the whole car.
starting with the roof.. I followed the exact same steps as on the fender but the roof came out way different. tons and tons of scratches left over.. some deep, some shallow.
after hours of research I tried a few different systems. Sanding up to 3000 between each trial and working clean.
-Meguairs Ultimate compound/ultimate polish
-Meguairs Pads
-Griots garage pads
-Chemical guys optical compound/polish
-Chemical Guys hexlogic pads
-Different brands and grade of towels
-Rotary machine
-DA polisher
My best results so far are with the Chemical guys brand stuff using a portercable DA but im still not happy with the results.. theres no shallow scratches but several deep scratches..
so my next thought was to go all the way back down to P600 grit which is what I originally sanded the car with before respray and sand up to 3000... then buff.
did that today and the results were not so good...
im so confused.
