Stage 5 is all of the above - plus two stage paint restore - final machine buffing - paint sealer.
Maybe Manny can jump in and explain this process a little more accurately.
I noticed the paint on my car looking "cloudy, almost grey" and even with going down to just the paint I could not get it looking any better. I was not comfortable at all with taking a buffer to the finish. Manny's guys did a great job and I am really pleased with the result. Hope this helps.
Thanks for the comments guys, I really like the car.
