Hi,
Hopefully i could shed some light for u.
85% of my clients' car are relatively new there swirlmarks, marring are at it minimal so to speak.
When I encounter with a situation like this...i would do hand grooming. MEaning no machine what so ever...strictly elbow grease.
But I do have an aid..the Polishing Pal to apply what eva not on the car's surfaces. BUt of course with different colour pads to suit the werk and application.
Starters, it proved to be tedious, tiring and not to mention the amount of sweat i get..possibly could fill up a bucket..aided with the tropical weather here where it could get as hot as the mountains of Mordor! khekhehekhkehkehe
After a couple of cars..i get the hang of it..and able to do it within 3 hrs.
As for the products used for hand grooming..me..i used a different type..am using Duragloss products, easily remove by hand alone...while machine..i would used Pinnacle Advanced swirl remover or Menzerna..
Hope it helps...
Cheers
