I don't think you can be an astronaut on the ISS without being a handyman, and the handyman's secret weapon is duct tape.

Trust me, grab some yards of gaff tape and try it out. You’ll thank me later!

In general, gaffer's tape is the superior product, but for this use case, I'm thinking that duct tape with its solid backed film and thicker adhesive might be more airtight.
