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.

  • 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.
