This client has been with me for a couple years now and first came with a 335is. He recently purchased this brand new Santorini Blue M3 of which there are only 10 of in Canada. It had some light swirling that was to be polished out and then Opti Coated. I mentioned Pro but in the end we just went with 2.0. This was a 1 Stage Polish to buff out the light swirling.
Getting started with the rims, which came in black from the factory by the way
2 Bucket Method Washed as always
Clayed with the Nanoskin Mitt while the car was still wet
Then dried with a plush microfibre towel
Paint was measured in microns to look out for low spots or repainted panels
And we brought out a new paint depth gauge that can measure non metallic surfaces by using ultrasound. This thing costed $3000!!!
It can measure up to 3 different layers.
The front fenders are made of an "advanced plastic" according to BMW so the "32" is primer and paint and the "68" is clearcoat equalling 100 microns. Which is about right because the other gauge measured 101 microns on the door.
Next up was masking the rubber trim
