paint "boiling" in engine bay????

[greenhummer]

anyone seen small areas of paint "boiling" in the engine compartment? I see some in the front lip of the engine bay and some at the very rear lip - in front of the windshield wiper blads.

I also noticed tha the brake fluid reservoir cap was loose and needed tightening. This type of "boiling" could have been caused by brake fluid but the reservoir is a ways off from the spots affected.
