Clay bar turning green?

[flyboy320]

I have just recently bought a used XC90, and as such do not know the vehicles history.

The car looks to be in good shape, but I have noticed that there are small "bumps", about the size of the tip of a pin all over the surfaces, so when you run your hand along the paint, it feels very rough. My guess is that the car was stored outside, perhaps even under trees, and it might be from sap/insects.

So now when I go to use the clay bar (white bar), I notice that after some use, the bar is picking up some green color off the paint. I'm almost %100 sure the car has never been re-painted (the cars color is light green/silver, but mostly silver), so I'm left wondering what this green could be from. I'm fairly sure its a different color than the paint itself. After using the clay, the surface is as smooth as glass.

Anyone have any idea, or seen this happen before?

If you take a white cloth and a cleaner wax or polish and rub on the paint and you see color on the cloth then it's a non clearcoat or a clear that has worn through. Those bumps if you pick them off and they are a red burgandy color then I see them all the time and hate em. Clay seems to take care of them the easiest.

You could have picked up a sort of Moss or something like that. That would explain the green color. I couldn't tell you how moss might have grown on your car though, just a random guess.
