Please refer to the picture : I got a touch up job done at the (RED MARKS) .. the paint merged fine but in the end the guy put some oil over ( YELLLOW MARK) to protect my hood from rain( IT WAS GONNA RAIN THE DAY HE DID THE JOB) now that oil has left the stain.. i tried cleaning it with different cleaners and removers including goo gone now in the end it jus looks like this dull and weird .. i asked him he said to polish it ? but before i ruin it more i want to know if anything else i shuld try because i hardly doubt polish is going to fix that stubborn oil mark

 

anyone?
