if your serious about detailing and I mean serious, as in have 6-8 hrs to waste, this is the order of detailing you should follow,
Wash & Dry -> Clay Bar -> Cutting Polish -> Finishing Polish -> Glaze -> Sealant -> Wax.
this is the difference to most peoples details, compared to a serious detail.
regular detail (1-2 hrs spent) using bare minimum products, ie. wash/wax.
notice the house in the reflection
now here's with an 8 hr detail with, Wash & Dry -> Clay Bar -> Cutting Polish -> Finishing Polish -> Glaze -> Sealant -> Wax.
now notice the house reflection.
thats the real difference.
