Weird Smell in Shop

[Fuddyduddy1952]

You might have phantosmia, a condition where you smell things that aren't there. I'm pretty sure I have it because I often smell smoke that isn't there.

Could it be mildew from a roof or wall leak? Maybe something in storage like a paint can that has rusted through and is leaking.

Thanks for "phantosmia" which I'll now say to the wife when I expell gas in the car.
