Removing Scratches

I'm putting my car up for sale tomorrow, and during the day i want to go over the exterior to rid it of minor scratches and/or swirl marks, what product(s) would you guys recomend???

coarse sandpaper

lol... why not poop?

If you're good at wet sanding, that would be a way to get rid of some. If it's through the paint, you're out of luck without repainting it...

Any fillers or wax or glaze or something i could use a little less abrasive???

i'm sure they got all kinds of scratch removing products at the local autozone/advance auto

Your best bet would be to get it done by a detail shop. They know exactly what to do to get the entire car spic 'n' span(engine, wheels, interior,& paint) It might cost you a few bucks, but it's a good investment if you're going to sell the car.
If you just want to make it look descent, you might want to look into a mild rubbing compound. But watch yourself, you can rub right through the existing paint.
