Help me find out what this is. It was a spacey sci-fi thing. It had a guy in spacesuit who gets a hole in it . He patches the hole and the epoxy/glue in the patch bulges out in a large bubble . I can't remember if he snuffs it or not. It couldn't have been that strong or adult a film because I remember this from my pre-school days ie mid 1970s. I was wondering if it was UFO but I never really watched that as a kid. any ideas? This has bugged me for literally decades!
