Does look kinda Nasty huh!
I can't quite tell, is that corrosion being generated as a result? Do you live in a rust prone area?
Well if that's A/C drippings I suppose your choices are to re-route/extend hose someplace else (my 3G drops it onto the exhaust pipe). Then clean off the mess/paint/protect it somehow. Hopefully its not your battery draintube...Luck! :banana:
