난이도 & 준비물

증상

Having decided that it was time to move on from the C Class we bought in January, it was time to start looking at replacements.Initially an F31 3 series was the preferred option and a return to my safe place, however they all seemed really bloody expensive and it was hard to find at least a 320d with the options we (well, I) wanted. Anything half decent seemed to get sold instantly. I missed out on a higher mileage 330d x-drive in red that had some nice options and a massive stack of history with it.We looked at a 320d not far away in white with red leather but there was a fair bit of rust sta

처리 내용

Once the rain cleared up this morning I decided it was time to get stuck into the outside of the Cayenne.It was still pretty clean, so I coated it liberally in Bilt Hamber Korrosol. Being a black car, it was hard to see much reaction with contamination but looking at the floor, it was clearly doing something.The only place it was visible working was on the chrome strip on the bootlid.After rinsing off the Korrosol, I went over the car with Car Pro Tar X because on closer inspection, there was a lot of tar on the car especially on the plastic trim around the arches.The Tar X soon started doing its job although it didn’t shift all of the tar spots.After another quick rinse, it was time for snow foam with Garage Therapy Zero so help deep clean the paint.After rinsing, washing it with Zero and drying the car, it was time to break out the clay bar. The paint felt really rough when drying the car. It didn’t seem too bad to start with.But, it didn’t take long until it was like this every area I did. The bootlid was pretty bad.The paint looked pretty rough, a mixture of scratches, swirl marks and marring from the clay bar.After a couple of passes with a purple hex pad and Scholl S20 it was looking much better.Given the lack of tune today and the state of the paint, I decided that today was about improvement rather than correction especially when factoring in the size of the car . In the spring, it’ll get a proper two stage correction, probably over two days so I don’t get bored.The bonnet reflections were soon looking pretty good.Poor attempt to show a comparison beware the polished and unpolished rear passenger door.Once fully polished, the car was washed and dried to remove polish residue and dust (I did get a bit lazy….its a big old bus). Once dry, I wiped the car down with Stripped Ease before applying a coat of Soft 99 Fusso coat with was then topped off with a ceramic detailer.I then popped out to get a few better pics. Looks pretty good for a 16 year old behemoth tha
