I will just copy and paste this from our Forum. Easier than switching all the tenses and changing words...
-------------------------------------------------------------------------------------
I had been waiting for a good 'test subject' to perform a full paint correction on using the new SCG Pro polishes and luckily this 750Li belongs to a friends dad. Lots of swirled up paint (forgotten how big these 7 series actually are) to show what the polishes are capable of and since the job was performed free of charge I knew the owner would really appreciate me giving his car a makeover.
DIAGNOSIS:
It was purchased used from a dealership with relatively low mileage (currently only has about 36k) but its time with the previous owner and the dealership were not kind. Plenty of swirls and it had clearly seen a rotary hack job sometime in the past as holograms were present on almost every single panel.
Aside from the swirls and holograms the paint had the (to be expected) small pitting on all the forward surfaces, but otherwise the paint was a prime candidate for correction.
The wheels were only mildly dirty, the interior was spotless save for the usual skin oil transfer on arm rests and the steering wheel, the interior would be saved for last as a light cleanup since not much else was needed.
Aside from being dressed with something silicone/sticky the engine bay was almost perfect. Minimal effort would be needed there to remove the dust and knock down the sheen of the existing dressing.
EXTERIOR CLEANING:
Luckily I had Chris aka Mook assisting and we got to work quick - this was going to be a job done over a few day span, a little at a time so an extra set of hands made for faster processes.
We went to work on the wheels first. Mook with a stiff brush and 4:1 dilution of SCG Pro All Purpose Cleaner Concentrate on the rubber and fender lining, I attacked the wheel faces with SCG Pro Active Wheel Cleaner Plus and a black boars hair wheel brush. Lug holes and smaller areas were addressed with the 1" round boars hair detail brush.
cont'd...
PAINT PREP & DECONTAMINATION:
The paint clearly had some kind of wax or sealant still on the exterior, so SCG Pro Surface Prep Wash was going to be used to remove that before moving into clay.
The exterior was rinsed thoroughly with a pressure washer (40* fan tip) to dislodge as much of the dust, dirt, and debris as possible before moving on. Using my MTM Foam Cannon we pre-soaked the exterior with a 3oz mix of Surface Prep Wash. Slightly stronger than normally needed, but since we were unclear about what was on the surfaces and there were some areas with sap contamination it made sense to up the strength a little to cut thru that.
Dividing the car up, Mook took the lower sections using a fresh synthetic wool wash pad, while I took on the upper 2/3rds using our Merino Wool Wash Mitt. Per usual we still incorporated 2 buckets with grit guards to keep more prep wash in the mix, but also to rinse the mitts after each panel to prevent new damage.
No sheet rinsing was done, mainly b/c after the prep wash the water was no longer beading and wouldn't have benefited, also because we were going to clay 'wet' the additional water standing on the surface would help.
cont'd...
The car was then pulled into the garage so we could clay out of the direct sunlight. A 64:1 dilution of SCG Pro Rinse-Free Wash & Wax was used to provide lubrication for the SCG Pro Fine grade clay bar. Each panel was saturated and clayed until smooth. As you can see below the car had some kind of overspray or fallout on it as the bars were very dirty even after just the first panel.
After claying it was pulled back outside and given a quick rinse to remove any excess residue from the lubricant. Back in the garage again it was dried using 2 waffle weave drying towels. No drying aid was used as we wanted to minimize anything on the surface prior to starting correction.
Water was blown from tight spaces using a Metro Blaster Sidekick and door jambs were dried using a few shots of the diluted RFWW and our light blue microfiber utility towels.
After claying we got an up close look at the paint condition and it was about as bad as expected:
