My car scraped against a rusty pole (it was lower than my window, I couldn't see it). So it scraped up my paint a bit but mostly it's just got rust on/in the paint that came off the pole. My buddy told me it was a "that'll buff right out" kind of thing. I don't know much about cars and I don't have the money to take this to the shop right now but I'd like to clean it up a bit. I don't mind the paint scrapes but is there a way I can get that rust off/out at home with common or inexpensive materials?
