anyone else having this discoloration?

My car is black too, and while it's not as bad as both of yours, I can see the circles too.

no mysterious crop circle's here

Are the holes above drainage holes?? If so the water you are using (or rainwater) maybe has a high mineral content (or some other chemical(s)) which is causing some kind of reaction in the plastic.

Just checked. Nothing here. I have never lived in the Pacific Northwest, but it rains here more than anywhere I have ever lived. It is garage kept, but sits out all day at work

my guess is mineral build up since you live in texas.

some mothers back to black should cure that.

wow that was an interesting rhyme...

But if its water leakage then that means water is getting inside the hood somehow. We can test that theory: The next time you wash your car then spray it down real good and pop the hood. You should find water beads sitting in those exact spots.

Warm, moist air condensing as the temp drops, leaks out of the holes directly above the spots, possibly bringing with it some errant paint particles, chemicals, etc.

Sounds like a good enough theory to me...

you may be on to something there... i know this is not being caused by water entry during a wash or anything else, like rain, but it could be condensation as you are theorizing. i know it's not rain because this car was a rain virgin up until yesterday. also, i always pop the hood after washing and clean up whatever i can after the outside is done and i have never seen water in the engine bay aside from the edges where the hood meets the the body after washing.

the thing is though, the way these discoloraitons look is almost as though they are not caused by water, but by gas or hot air. there are no circles or mineral build up like one would see when water dries. but nevertheless, it could be water.

all in all, i'm just glad that this is an extremely minor issue and isnt affecting performance in any way (that i know of).

thanks for all the feedback, everyone!
