Jazakallah for ur mesg , i still remember ur Skardu visit thread and it was really amazing 
removing / minimizing scratches require abrasives like compounds or even in severe case wet sanding and it require experties.
i would propose propose
1) meguiars ultimate compound rs1200
use with microfiber pad in small sections at a time like if working by hands than 1x1 feet with firm hands and work till product vanish than remove residue with clean microfiber cloth
2) meguiars ultimate polish rs1050
use with foam applicator pad or microfiber applicator pad in small sections at time with medium hand presure and work till product vanish than remove residue with microfiber cloth
3) meguiars hi tec paste wax#26 rs1350
comes with foam applicator pad , apply softly one panel at a time than buffout residue and go to next panel
apply very less qty of wax
