What has happend with the paint?

[allenk4]

Call the Owner and ask him if the car was stored under a cover and if so, how long ago was it uncovered

As others have stated, it looks to be the likely cause of the pattern on the roof

Hopefully, the pattern will even out. Megs #7 might help

I would PM Mike Phillips to make sure he sees the thread

I talked with the new owner that imported the car from usa to sweden, he also told me that he used some kind of degreser when he washed the car. And i asked him more about that, and he was not sure if it was petrolium based or alkaline? ( dont know the english word for it) could it perhapes been that that coused it?
