It is also one that works great with sailboats and power boats alike and it bonds well to fiberglass, wood, and prime metals.

 

It does not matter if your vessel will be spending most of its time in freshwater, saltwater, and even brackish water, because it holds up very well in all situations.

 

The finish on this Interlux bottom paint is very tough and with the slow self-polishing process it will hold up well to prevent marine growth and can produce season-long protection.

Total Boat JD Select Bottom Paint.jpg

Being one of the few bottom paints on the market that offer low Volatile Organic Compounds (VOC), TotalBoat JD Select is very cost-effective and one gallon of this stuff can go a long way. This water-based paint can cover about 400 square feet per gallon and is ideal for fiberglass, steel, and wood boats.

 

JD Select is very easy to apply and is an absolute breeze when it comes to cleaning up because it is a water-based paint and only requires some soap and water to do the trick. Don’t let that fool you into thinking that it is unable to do its job though. 

 

JD Select is a very effective anti-fouling paint that has a concentrated biocide in its formula and works well in fresh and saltwater.

 

Considered a single-season protector, it works well at combating barnacles, weeds, and slime from clinging to the bottom of your sailboat or powerboat.

To get the best results with this paint, you will want to apply 1 to 2 coats with a roller, a brush, or a sprayer. If it seems a bit thick, then you just need to thin it out a bit with a little water beforehand.

Color Options:

  • Black

  • Blue

  • Red

  • Green

 

Depending on what the temperature is outside, you can reapply additional layers after about an hour and a half wait between layers and then launch the boat in about 6 hours.

The water-based formula makes for easy clean-up

Low VOC and low odor

Easy to apply and dries very quickly

Great for speed and fuel efficiency

Can be applied over most anti-fouling paints

4. TotalBoat Underdog Review

Total Boat Underdog Antifouling Bottom Paint.jpg

This single-season ablative paint from TotalBoat is best used on fiberglass, wood, and steel boats to provide the best protection from marine organisms, trailering, and beaching. Once this stuff dries, it holds up very well to frequent use and is perfect for sailboats.

 

If you choose to go this route, you can rest assured that this paint will put up the ultimate fight against marine fouling by releasing fresh biocide, as your boat moves through the water, to repel those pesky barnacles that want to attempt to make a home on your vessel's hull.

 

On top of it being able to combat fouling activities very well, it has great results at preventing paint build-up, which will make it easier to apply fresh coats each year, and who wouldn’t enjoy the fact that it is very economical in price considering the job that it does.

 

A gallon of this paint goes a long way with the 500 square feet that it can cover with each gallon and is easy to apply with either a roller, brush or spraying.

Color Options:

  • Black

  • Blue

  • Red

 

Underdog by TotalBoat is best if you apply 2 coats and allow at least one and a half hours of drying time between each coat for temps at 90°F and 3 hours for temps at around 70°F and 6 hours at 50°F. 

 

Relaunch of your boat will require a wait time between 6 and 16 hours depending on outside temperatures.

 

  Pros:

 

Perfect for boats that are used frequently

Fast drying times

Economical price point

Very durable against abrasions from trailering and air exposure

Does not require sanding between new applications
