This two-part epoxy coating was developed to protect fiberglass hulls from water absorption. Available in gray or white, Interlux’s Interprotect 2000E uses micro-plates to create an overlapping barrier to help keep water from migrating through the coating. You can also use it on virtually all surfaces (including metals) as a universal primer, both below and above the waterline.
