I might try using a clay bar first. They're non-abrasive and they leave the finish feeling and looking like glass. I'm a big fan of Zaino products but you can get a clay bar and the lube needed at most auto parts stores. If they don't sell the lube, you can just mix a couple of ounces of car wash concentrate with water into a spray bottle and use that. It's works just as well and it's cheaper. Good luck.
