The $18 tube lasting through two monsoon seasons is the part that gets me. I did the same thing on my back steps last spring, grabbed the siliconized stuff instead of the basic latex. Watched it through one summer and a nasty hail storm and it still looks brand new. Worth every penny when you don't have to scrape and redo it every year.

Four hours for one shrimp seems like a lot but I get it, that smell takes over everything and you can't think straight until it's gone. Honestly though, a single rotting shrimp behind a door gasket is pretty low on the list of gross things that could be hiding in a walk-in. I'd be more worried about what's growing in the drain line or inside the fan housing where nobody ever looks. Count yourself lucky it was just the shrimp and not something dead in the walls.

Did the enamel chip into your food?
