Have you tried leadmate ? Its very good stuff and it worked in the wet when i used it. We had a bad leak above our bay window and i got out on there in the rain and sealed it up and not had another leak since and that was 2 years ago. You can get it from builders merchants or i think places like screw fix do it. I had a few tubes which a roofer left on a site i was working on but threw the rest away as they had gone out of date
