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!
