Interlux ACT with Slime Fighter Antifouling Marine Paint

Interlux ACT provides excellent season-to-season protection with Ablative Technology. Ablative Technology enables ACT to erode away with use and eliminate build-up of old spent coatings and the heavy sanding needed to remove them. Interlux ACT is very effective at controlling shell fouling such as barnacles and zebra mussels and contains a Slime Fighter to control weed, slime and algae growth which helps to keep the boat bottom cleaner longer. It provides excellent protection against all forms of marine fouling in waters with moderate to heavy fouling and can be used in fresh, salt and brackish waters. Also, Interlux ACT can be applied over most other antifouling paints provided the old coating is tightly adhered and in sound condition.

Do not use on aluminum.

Excellent product, will continue to use it.Review by Captain Bill
Have been using this product for over 15 years on the same Fiberglass boat. Boat is in water all season in New Jersey waters. Never have to sand, paint build up is minimal and marine growth is non existent. Able to use less product each year for the same area of coverage (Posted on 10/18/15)
This is after 2 seasons use and re coated each seasonReview by Old Mud
This paint works somewhat better than previously applied black, but pricey. (Posted on 10/14/15)
