Any compound with a heavier cut foam pad on a dual action polisher will remove those marks or at least greatly reduce them. I would follow up the compound step with a polish and a light cutting pad. I'm a big fan of the Meguairs M105 and M205 combo with Lake country pads. I would start with M205 on an orange or white pad and see if that removes the marks, If it does good. If not, then go up to the M105 on a yellow or orange pad then back to the M205. 5" pads with a 5" backing plate on a DA polisher is your best bet. Harbor freights DA polisher is actually pretty decent and doesn't brake the bank to much. I've been using that machine for several years with out problem, I did throw out the crappy backing plate that comes with it and got a Meguiars 5" backing plate.
