Appearance & Detailing - 2011 BMW 535i Full Paint Correction

This vehicle saw another detailer at a body shop to get some water marks removed and they ended up ruining the paint. So I had the opportunity to bring the paint back to life.

It's so quiet! What types of products did you end up using to correct the paint?

Looks good but I hope the owner didn't pay much for it the first time around.
