aquire a case of man up and start the monotonous task that is polishing.
Best technique ive used...
Jack the rear of car up
SECURE stand, block the front.
Attach wheel
hose
turn car on and put in first
wet sand paper on wheel and hose every couple of turns to keep wet

Hours hours hours later you might get something like this
