u-pol is a great primer, thats what i use. it will fill a 80grit scratch and can be baked to sand in 15 minutes.
also, when you get there, use their clear. it is a very high solids, meaning you get more build per coat (like twice what you get with ppg and others). Plus you get more for your money, we pay $180 for over a gallon of clear, hardener, and reducer.
