Paint problems - is that limescale? & above all - how does it go away? THANKS

  • Where did the boss stand? Is that residue on the paint or in the paint? It's hard to see with all the reflections.

  • ... looks more like UV-damaged paint to me.

    We once had this with a vehicle after a visit to a car wash. The wrong cleaner was used there and it was due for a complete paint job.

    Is the clear coat "soft" in these areas?
    If so, it is "broken", if not, a paint cleaner may still work.
    Is it just the hood and has it been repainted?

    Greetings Stefan

    Servus,


    I have not been to the car wash or an external wash bay with the car.


    It has "spots" on the surface - don't know if you can see them in the photos - and I think it's raised on the paint, so to speak...


    Clear coat is not soft. Damage is only on the boot lid.


    Unfortunately I don't know if it's been repainted, I've had the car since 2015 and it wasn't a new car... is now in its 25th year...


    thx

  • I had similar spots on my CFRP hood. It looked like these milky streaks were in the clearcoat. I went to my painter and left it up to him how to get rid of the stains, from polishing, local sanding and new clearcoat with polishing or painting the whole lid.

    It went away with polishing and the hood looked like new again.

    Greetings
