While I'm not sure myself - I'd check around ports (headphone jacks, near the keyboard, power plugs) they tend to be located around openings into the cavity.
If you got one wet, and are trying to hide it - I'd quit now while you're ahead - water damage is OBVIOUS to just about every electronic technician, even if you dry it out. The level of effort required to mask water exposure isn't worth the cost of a replacement.
That said, good luck!
