I remade and replaced my portlights about 4 years ago and used Life Seal as well. It is a combination of polyurethane/silicone and has not leaked yet. DO NOT USE POLYSULFIDE on the portlights because it will attack the portlight material and result in problematic leaks until they are replaced (experience speaking!) B. Cox
