Yep, it really does depend on what liquid they used.  I used to have a set 
of marker pens for measuring the stickyness of surfaces (I forget what the 
scale was, but they were numbered 1-50 or something).  The 1 was like 
mercury, it would stick to nothing (not even normal paper) and would always 
form blobs.  The 20-30 would mark and stick to pretty much anything (like a 
permanent marker).  We were using them when we had problems with print not 
sticking very well to plastic wrap.  They could have easily used a liquid 
like I had in my marker pen #1 and it would pretty much "run off" of 
anything you put in it.

One of the most interesting uses of "nanotech" would be to keep your car 
windscreen clean, without the need for wipers or a cloth to get off splatted 
flies.
