## Description

Fiberglass Bottomkote NT uses a dual resin technology that provides a universal durable, fast dry antifouling paint that delivers the benefits of both hard and ablative antifouling paints for use on all power and sailboats. The universal formula of Fiberglass Bottomkote NT has durability of a traditional hard paint but has a slow polishing mechanism built-in that continuously smoothes and renews the active surface avoiding the heavy build-up of paint layers much like an ablative paint. The fast dry formula allows the boat to be painted and launched in the same day. Fiberglass Bottomkote NT provides clean stable colors for effective season-long protection. Fiberglass Bottomkote NT is recommended for use on the underwater areas of fiberglass, wood, and properly primed metal [except aluminum] boat hulls. It can be used in fresh, salt and brackish waters.

## Customer Reviews

### ⭐⭐⭐⭐⭐ good for fresh water boats
*by T***E on June 28, 2025*

Why did you pick this product vs others?: easy to apply, good coverage on 322 MY. Better $ than West marine

### ⭐⭐⭐⭐⭐ Very good quality
*by G***S on August 28, 2025*

Very good quality paint

### ⭐⭐⭐⭐ Goes on easy, wear a respirator not a dust mask.
*by N***E on August 9, 2025*

Very low viscosity, a lot closer to the consistency of water vs paint. Covers well, one gallon did 2 full coats on our 27' Bayliner and still have enough left to probably do a 3rd coat at fall haul-out. Has kept the bottom clean so far this season. Using a 3/8" nap roller leaves a nice hard slightly textured surface. I applied over four coats of 2000E. Strong smell and probably not the kind of stuff you want to be breathing, it's a biocide after all. Wear a cartridge respirator and not just a dust mask. Mix it well with a drill and mixer and scrape the sides and bottom of the can to get it all uniform. It would be a tough job trying to mix with a stir stick. Happy boating!
