What about Polyethers? Flexible, adheres to plastics (3M 4000UV does anyway). Here’s what West Marine says about them: Polyether: One of the most exposure resistant sealants, unaffected by teak oils or cleaners, permanently flexible, and sandable. West Marine Multi-Caulk is an excellent choice for wood, metal, or fiberglass but will attack some plastics. However, 3M 4000UV <https://www.westmarine.com/buy/3m--4000-uv-polyether-adhesive-sealant-white-10-oz-cartridge--3760196> is rated as being safe for all plastics. Ed
