Lacquer becomes cloudy milky after polish

Tachchen, I had completely polished my car about 3-4 weeks ago.Sequence: 1. wash 2. knead 3. wash 4. bad places with sanding polish 3M green 5. polish with 3M antihologram polish 6. grow in, first with A1 Speed Polish. Afterwards I had everywhere in the paint, which did not go away. I guess it was residue from the polish that were now sealed. ;-( So again step 4 to bring the wax down again and then again step 5. Then I applied Sonax Wax. The result was perfect. Absolutely no holograms and very nice shine. Fly residue can be washed off simply with the high pressure jet. BUT Bin On Friday by car 5h in the bright sun drove to Austria. When we arrived there the paint was suddenly totally milky in some places and you see where I am along with the polishing machine (excenter). How can that be? The car looked great 3-4 weeks and now that? I need to get help, don’t trust me on the street as he looks now.
