I ordered some fin plugs and vented leash plugs from you. With those vented leash plugs you sent me a green chewing gum like mass. Could you tell me what's that for? The chewing gum like mass is Epoxy Putty, it's used as a resin dam during installation so the resin won't clog the G-Vent membrane. You can watch the Vented Leash Plug install video here showing how the putty works.
