Here is the place to find the select Epoxy Additives, Thickeners, and Fillers you need for most boat building, repair or finish work. Look here for Wood Flour, Colloidal Silica or Polyester Microfibers, which when combined with epoxy resins and glues will add structural and finish material to hull, deck or bulkhead. We also stock Barrier Coat Additive to enhance the moisture barrier of an epoxy finish. The resins, glues and other epoxy compounds can be located throughout this category of our web catalog.
