Showerthought: my kid's toy camera made me rethink light seals
The cheap plastic shutter on his plaything jammed open, so I used a sliver of black craft foam to block the light path. Anyone have a better material for a quick seal mock-up before cutting the real stuff?

Black craft foam... might it outgas and fog the lens later?

Yeah, that outgassing thing is a real problem.

My 1980s Nikon sat in a hot car trunk for years with a foam light seal that outgassed like crazy and never fogged a single frame. Unless you're sealing the foam inside the lens cavity itself, the amount of gas from a craft foam sliver is negligible compared to just dust and humidity.
