Q. Which acid effects sheet metal the most.

A. Hi Marie.

I remember a 1970's Michael Crichton movie called "Westworld", where Richard Benjamin goes on vacation to an animatronic/robotic re-creation of an "Old West" town. Then a robot cowboy, who looks like Yul Brenner but is actually made of sheet metal, goes bonkers. As the robot attacks, the hero finds himself cornered in a laboratory full of glass bottles of acids: acetic, sulfuric, hydrochloric, nitric and so on. His survival depends on throwing the right bottle of acid at the robot since he only has time to throw the one.

Is this more or less what you mean, which acid would be most devastating to a sheet metal animatron? He picks hydrochloric. Now the question is whether the movie has a happy ending :-)
