Porsche 911, Red paint ?s

My friend has a mid-late 90s Porsche 911 (original red paint), The exact year I'll find out later when he gets off of work...



It has horrible spiderwebs and a dull finish. He had a local detailer take a look at it and the guy tried to clean it up but when the owner/friend saw that the buffer had red on the pad he told him to stop immediately!



He called me and asked if there was anything special about the paint, such as no clear coat?



My question is sort of...



I know that oxidation will make the pads turn the color of the car, but from what he told me it was like the car was bleeding. Dark color on the pad.



Is there a process (special for a Porsche) of getting the paint back to it's beautiful shine and luster for a Porsche?

or would I just go about detailing it like most other cars?



Is there any other info that is needed?

Thanks for the help!
 
Oxidisation is the fading of the very top layer of paint on a car - this generally happens to cars with no clearcoat and is in great part a result of UV damage - cars with clearcoat have there colour coats protected from the UV to a great degree... Reds are particularly bad for oxidisation, as they absorb the colours at the blue end of the spectrum (higher enegry) and the UV rays. The reason you see a car as red is that it absorbs all the other colours (blues, greens etc) and reflects the red which you see.



The fact the car is "bleeding" is nothing to worry about if the car has no clearcoat - in order to restore the original lustre you have to rmeove the uppermost layer of dead faded paint to get back to the original colour, and this uppermost layer bleeds on the pad and turns your pads red. All single stage red finishes will do this. If its bleeding a clightly darker colour this suggests to me that the paint being removed is not "clean" and there contaminatns in there as well, and also it should come up a darker deeper shade than the faded red.



As far as working on this car goes, I would go for a light to medium abrasive like Meguiars #80 or Menzerna PO106FF Final Finish on a polishing pad, and if necessary step up to something like Meguiars #83 or Menzerna PO85RD3.0x Intensive Polish if the oxidisation is bad and the paint hard. Once restored, feed the paint with a pure glaze - on solid reds I can think of no better glaze IMVHO than Meguiars #7 Show Car Glaze, gives an awsome deep and glossy shine. Then protect the finish with a good quality wax - Meguiars #26 I find sits really nicely on #7 but any good qaulity wax will work well.
 
Thanks for the good info!



Would you or anyone else know if this car has clear or not? I'd like to answer his question before I start on the car.
 
Cannot answer with 100% certainty mate, but if its already pulling pigment I woud hazard a guess to say that its not got clear... also, I recall seeing a Guards Red 944 (mid to late nineties IIRC) that was faded to pink and that car had no clearcoat.



Im sure someone will be able to chime in soon with a definitive answer for this car.
 
Its called a single stage paint.



The color. reducer, and hardener are all mixed together and sprayed.





Two-stage paint:



Color and reducer are mixed and sprayed

Clear, reducer, and hardener are mixed and sprayed after the color had time to flash.





Three-stage paint:



Color and reducer are mixed and sprayed

A translucent or pearl(-escent) is mixed with reducer and sprayed after the color had time to flash

Clear, reducer, hardener is mixed and sprayed



There are variations from manufacturer to manufacturer (paint not car) in the mixing of clear, pearls, hardener, and reducer.
 
I just did a 89' Turbo Saturday which had some oxidation. If I would have seen this tread before hand I would of taken a pic of the car and pad. Dave KG is right on and agree 100%. You could call the local Porsche service department and ask a tech. Might even be able to measure the paint thickness as a clue as well. Single stage paint may or may not be as thick as other stages. My process was Meguiars #80,#7 and Meguiars Carnuba.
