Funny smell in the garage… looked everywhere, there must be spilled mineral spirits or paint… did the girls spill nail polish cleaner, or throw it in the garbage? Why does it smell… search and search, and I hear a slight hiss, its in the corner, its on a shelf, but what can?  Something under pressure, so must be a spray can.  Process of elimination, take one can off after another…. its the Rust-o-leum!  How does a Rust-o-leum can rust?  Rust through and then start leaking.  Can’t say much for this product’s purported and intended use 🙂
