For what it's worth...It takes me five to six hours on a SUV. Tires, wheels and barrels, wheel wells, exterior foam down and wash, clay, HGG, VRT, clay and seal windshield. Interior vacuum, mats, all surfaces with either Interior Detailer or Leather and Interior Cleaner, spot upholstery cleaner when needed, windshield with Brilliant Glaze. However, remember I am relatively new at this and do it in my spare time only.
