Paint bubbles???

Just walked past my Boxster parked on the drive and was gobsmacked to see an area of the rear wing covered in tiny bubbles (not unlike orange peel effect). This area was previously perfect and I have had the car for over a year and a half now, so it's not recent bodywork. The reaction has happened in the recent past as the car does get the occasional clean and it's obvious enough for me to have noticed it before.
Has anyone else suffered similar problems? I am guessing two schools of thought here, other people have had the same and it's something to do with water based paints or my car has had some paint work in the past and it has reacted. Stunned if the later is the case.

    Definitely paint bubbles and not hardened tree resin? Also, as you will see in your service book; Porsche only give 3 years paint warranty but give 10 years body corrosion warranty... do they know something we don't?

    I would doubt it's tree resin as I have tried to cut the area with a mettalic t-cut and it did'nt budge and the car is rarely if ever parked under any trees (it has a fairly regular routine and is parked in almost one or two places). Also it's just on one panel, no other effected. It's most likely i think to be a paint reaction but i'm stunned that it's taken over a year and a half to come out?

    How about a picture Laurence?

    Very tiny bubbles are sometimes refered to as micro blisters. These are often caused by car covers being used especially if put onto a damp car or left on for long periods with temperature cycling. Do you use a car cover?

    nope car sits mostly outside and does'nt have a cover. Tried to take a few photo's but camera does not pick out detail well enough. I have just been reading up and yes blistering is the most appropriate description. Heres a quote from the book i have.
    "Blistering appears as pimples or bubbles, which can vary considerably in size and density, in the paint film. It can affect newly applied and aged films, commonly occurring during periods of high humidity followed by sharp frost spells.
    cause: Trapped moisture or air under a paint film causes blistering. Even the best paint films are permeable to water vapour, and when the paint film is subjected to abrupt changes in temperature , the entrapped moisture expands and builds up pressure this waekens the adhesion between the various coats and so leads to the formation of blisters."
    Seems the recent weather conditions have brought out a latent problem, possibly from a previous minor repair in the dstant past, the area is very localised. Looks as if i will have to chalk this one up as bad luck.

    This has just happened to me today! Cleaning the car ready for the Christmas meet tomorrow and noticed micro blistering. Car has been in my possession just over a year and not had any paintwork done with me, so shocked this issue has only come out now.
     
    Car is normally garaged, but spent the past two weeks on my parents driveway where the frost got to it.
     
    Presume the only remedy is a respray?
     
    Hoping I will get some advice from club members tomorrow at Bicester.

    This happened to our Z3, as said it's tiny micro bubbles  that get worse and worse its moisture under the paint or lacquer that will eventually peel 
    Only remedy is a respray and the bubbles need sanding back pretty hard to remove all trace, my mates got a bodyshop  and almost took it back to bare metal.
    Good luck hope you get it sorted.
    PS our blisters appeared last year after a few days of hard frost.
