Do you have pictures so we can get an idea of what you are dealing with?
Basic rule is if you can't feel the scratches with your finger, you can remove them with a DA Polisher. If you can feel the scratches with your finger, you're going to have to wet sand. If it is through the clear, you're going to have to repaint.
There are a few polishers that are safe to use on paint and don't generate too much heat. A Porter Cable is your safest bet.
Either way, post up pics.
