Life Caulk does not stick to Starboard. Almost nothing sticks to Starboard, since it is a high-density polyethylene. The only caulk I have found that does stick is System Three SA-2100, which is a water-based 2-part polyurethane, and the Starboard needs to be corona-treated before application, then left for a month until the 2100 sets up firm. Even then you can pry it off with a bit of determination.
