Is it even possible?

When I do my PC work for friends and family, who aren't auto enthusiasts, I make sure they know I won't be removing the swirls. It's usually just a clear coat cleanup and leveling, although some swirls are removed. No way could you do even a decent correction with 4.5 hours, I don't care if you are doing a Mini Cooper.

 

I almost solely detail subarus. Well subarus fords and nissans. And a few bmws. But I couldnt get a complete detail with a 1 step done in that time frame. ie wheels/ wheel wells, interior paint correction and a wax. Tips polished all that good stuff.
