The Z4 had some panels respray or/and some aggressive buffing before.
the paint was neglected for a while.
when i saw the car i plan for 2 step correction one compound one polish, so i kind of have m105 in my mind. knowing that the car has some "history" i took some readings around the car and i was surprise to find the hood into max 70 and min 48 with a constant 55 , and all panels around the car between 88-110. at that point compound was excluded and i was aim at max 50% correction from initial condition , and my paint gauge save me again....
