First, my main job is not "detailing" but rather more of a mobile body shop fixing minor repairs. We tend to fix a lot of clear coat scratches as well. I use an original Rupes LHR15 and wet sand down to 1500 grit. My customer base is dealerships ranging from Toyota to Porsche and everything in between.
The new D.A. Fine while used with their yellow wool pad is, in my opinion, a game changer. Fast cut but also leaves the surface almost flawless. For my customers, the finish is much higher than their expectations.
This combination has quickly become my "go to" to handle most anything from clear coat scratches to damage from bird droppings or hard water stains.
