Will the TSA let me take a regular size caulking tube (pretty large) of kitchen and bath silicone sealant in my carry-on? It's not on the list of prohibited items. It's not exactly a liquid or gel. It's more like a stiff paste, but it's not completely solid. If I have to check it, I think I'll just leave it behind.
What do you experts think my odds are, assuming that the TSO sees it on the display and I tell him exactly what it is?
And why can't the rule just say non-solid if that's what they mean?
You'd be better off leaving it at home unless you want to 'voluntarily surrender' it to TSA. Some of that stuff out gasses acetic acid when curing which rapidly corrodes exposed copper (smells like vinegar) - thinking what might happen if the tube was damaged besides the awful mess.
