Movie from the 80s? A group of people are on a spaceship that hit by meteors. They repair the meteor holes with expanding foam, but the pilot is stuck in her bridge and is exposed to radiation.
Meanwhile, I think there’s a saboteur on the ship. The ending fight scene he does from one of the other passengers spraying the expanding foam into his mouth.
Sounds kinda like Lifepod (1993), a solid TV movie with a good cast.

This is definitely the TV movie "Lifepod" (1993). Everything described in the question is in the movie: pilot on the bridge, radiation shields malfunctioning, she is exposed to radiation, debris punching holes into the lifepod, they seal the holes with the foam, saboteur on board, fight scene at the end where one of the males sprays the foam into Ron Silver's mouth.
