Here is another write up of a job I just did today on a 330ci. The paint was in pretty rough shape. FG400 saved me a lot of time!
Sorry about the poor white balance in the daytime photos
Started with a rim/tire/wheel well cleaning:
The engine bay wasn't too dirty but I gave it a good cleaning and dressed the plastic bits with G6 HyperCoat. Gives the perfect OEM look.
Washing time. Always with the two bucket method and Mr. Pink! I also scrubbed years of grime on the exhaust tips.
Went over the whole car with Riccardo Blue Clay. There was a massive amount of overspray on the passenger side.
Some pictures of damage:
Near perfect correct on the trunk. To achieve perfection would of required another day of work.
