Any other Porsches with growing iridescent spots on paint?


Recommended Posts

I bought an 08 Cayman almost a month ago and then these iridescent "rainbow" discolored spots began appearing all over the car and it continues to worsen.  They are not noticeable in direct sunlight or when it is dark outside, but quite noticeable during twilight hours.  It kind of resembles a thin "oil slick light refraction" appearance or residual soap though I only use Meguairs products to wash and then rinse thoroughly... only in the shade with the car cool.  I have been to several body shops and they shrug their shoulders offering all different kinds of theories.  The place I got it from says Porsche paint can do this but I am not believing that.  A couple people said it would not get worse but it definitely continues to get worse over a relatively short period of time.  Any one have any clues what would be causing this and how to fix it?  I would really appreciate any help or explanations.

Has the car ever been coated with those ceramic clear coats like optimum opti coat? Those look exactly like high spots in the clear coat, too much product was applied. you will need to find a detailer that deals with those products, If its high spots, they can be buffed out.

Thank you AWDguy as that is what I was suspecting.  The dealer I got it from claims it is a factory paint issue and to talk to Porsche.  Porsche says no such defects have been reported, their paint guy and a separate detail shop believe it is a surface issue and that is before mentioning to them what the GM told me they did to the car.

 

The GM stated they applied a paint sealant called "cilijet" (which I did not sign up for).  When I brought it back to the dealership they applied more without consulting me first and viola... its worse.  Any factory paint issue would have showed up by now so these facts seem very consistent that them applying this substance is what is causing these spots to appear.

 

So after the Porsche authorized paint specialist and the other detail shop mentioned it is a surface issue, I told them about this product and they seem to agree that it is most likely caused by this product either being applied incorrectly or the surface was not prepped properly.  I will try to get it buffed and send the dealer the bill.  Thanks

You can you thank the cilajet for that depth ness and shine in your paint. Those products are good and do what they ate advertised to do. Just too much was applied in some areas. Get those areas fixed and enjoy the shine. Note that with these products, you don't need to wax the car. Most of these ceramic products are supposed to last the life of the paint. I'm not familiar with cilajet so read the product description.

I don't think its getting worse, just that you are starting to see the spots better. I believe you will only see the spots in certain lighting & angles. Now you know what to look for, you are seeing areas affected that you didn't see before.

I could be wrong. And it could really be new spots showing up. I doubt it though. If that's the case then I don't know what you can do.

At first I thought maybe I was just noticing it more because I was looking for it, but then confirmed it was really getting worse as I was tracking which areas had it and which did not and areas that had it were getting worse.

 

The good news is also that it was confirmed to be the sealant being too thick (good call AWDGuy).  An area was buffed that had some of the worst discoloration and it was gone.  The detailer was shocked at just how thick it was and it took quite some time just to do a small area.  The discoloring was probably due to it being so thick that sealant underneath even more sealant was still trying to cure.  Trapped outgassing may be what causes the color... I do not know.

 

He coated the exposed area with opti coat... thin.  Quite a difference.  The exposed area you can see the paint clearly... the rest still covered with the thick sealant has a dark filtered look to it... kind of tinted.  The rest of the car will soon be stripped of the thick stuff and the rest of the iridescent blotches.  Thanks

      I am looking at buying a 2010 997.2 which has very low kms. The previous owner did not like the factory grey colour (not sure why he bought it new in that case) - so he has wrapped the complete car in a very nice looking, but of course totally non standard, white with a metallic fleck in it. The dealer who is selling it says that it can be removed, but I am worried about damage to the paint underneath. The service records are complete and the garage that has serviced it is not worried as it is mechanically fine and has had very little use. What do you guys think? Worth a punt or leave it alone?

      I'm down to deciding if it makes sense to take out all the typical road rash chips on the front bumper cover and up the front hood on my 996 MY00 coupe RWD, 6 MT Blk / Blk. Previous owner had been diligent with touch up blobs, but it obviously would be esthetically better to have the front clip redone with the exact water base L741 paint. Rest of the car is perfect. Black is easier to match than light colored cars, so I'm tempted.
      OPINIONS PLEASE : The car is original paint. Since values of our 996 ain't going up again for sometime, does a " re- spray " hurt potential future sale:
      Thanks all.
