Interlux Fiberglass Bottomkote NT (New Technology) uses Dual Resin Technology to provide the advantages in both ablative and hard antifouling paints.
This durable coating prevents premature wear-through, yet it has a slow polishing effect that keeps the hull clean & smooth without the heavy paint build-up you can get year after year with a traditional hard antifouling.
Because Bottomkote NT dries so quickly, you can paint and launch the boat the same day. Suitable for all substrates except aluminum.
REBATE: 2023 Interlux Spring Mail-In Rebate Program - see the INFO & GUIDES tab for details!

I have used this paint 2 gallons per year on 37 Egg for the last 10yrs. It is reasonably priced and ablative action is good enough for short North East April to Oct season. Other than light cleaning on waterline holds up well enough. I cannot compare to other but works for me.

I purchased a 3 gallon black and expected a rebate on it for at least up to 2 gallons for it like the rebate stated. Went through the whole process and they won't honor it. The rebate didn't say the 3 gallons were not eligible or what products were eligible. Just up to 2 gallons were rebatable. So disappointed. I blame Interlux.

Been using this for a number of years. Used to use a much higher priced product, then tried progressively cheaper paints, down to the ones that didn't work. This is the least expensive, but still quite effective, bottom paint I've found for use in our waters.
