Super"hydro"phobic, but with acid?

[Daecon]

Is it physically possible to have a superhydrophobic effect that repels specific liquids (such as acid) and not just water?

 

I'm posting in Lounge and not science because I was thinking about a specific scene in Terminator Genisys and it got me wondering.

 

Then I thought about if a mimetic polyalloy Terminator could render itself invulnerble to a Xenomorph alien's acid blood by reshaping its surface to be superacidiphobic (or whatever the proper term may be)? I guess we could just invoke the "magic technology" trope but suspension of disbelief has to be drawn somewhere.
