what he said on polishing the tank karyn. i polished the lip on my 10 holes with that method. just MAKE SURE YOU WET SAND. and keep it wet. you'll notice the water turning white and that means your doing it right. alot of elbow grease. i jacked the front of the car up and had someone tap on the gas instead of working my way around the wheel. Good luck!
