Note that the area struck thorugh looks slighly lighter and lacks any of the gloss of the surrounding paint... This lack of gloss can be clearly seen under the Brinkmann light:
normal area:
struck through area:
half and half:
A check of the struck-through area reveladed a paint thickness consistently between 75 and 80um:
So... there we have it, strike through.
Clearly, if this was a genuine car and a genuine detail, if you measures paint thickness to be around 85 - 90um then you would rotary polish the paint with G3, as you would get strike through with the above... The moral of the story here being that if you are going to machine polish your car, its always much safer to check the paint thickness before using any abbrassive polishes, especially harsh compounds.
