Recommended for use on all substrates exposed to marine biofouling. EP-2000 offers an exceptionally smooth, hard and flexible finish which is perfect for the racer who desires the fastest, cleanest, and whitest bottom. EP-2000 is not compatible with other existing antifouling coatings. To protect fiberglass from water migration and gel-coat blistering, prime using EP-PRIME 2000. Metal surfaces must be primed with EP-PRIME 1000 and EP-PRIME 2000 prior to application of EP-2000. DO NOT APPLY EP-2000 BELOW 60° F (15.6° C) or when relative humidity exceeds 65%.
