About as good as its ever going to look. Paint and body are just covered with damage... so buffing it, claybar, etc not going to make it look any better.
Miguires NXT 2.0 is amazing though. Goes on so easy and yet makes the car look awesome. I hated thier old Gold Class as it made the car look awesome,but took a week to put on and get back off it was so hard and labor intensive.
