TotalBoat Underdog is a dependable, solvent-based, single-season antifouling bottom paint that provides outstanding protection against barnacles and other antifouling pests, at a very affordable price, and in all water conditions. Ablative technology allows the surface to polish away over time, minimizing paint build-up and releasing fresh layers of biocide as the season progresses. This ablative action works most effectively on boats that are used on a regular basis. Underdog's durable finish also stands up well to scrapes from beaching and trailering.
It has excellent adhesion on fiberglass, wood, steel, iron and most existing bottom paints that are in good condition.
Sold in Gallons, in Black, Red, or Blue.
Each order includes a free roller & metal tray kit, paint suit, abrasive pad, 1 roll of painter's masking tape, & two 10" stir sticks (a $10 value!).

Seems a little thinner than most other ablative bottom paints, so ask me after the summer how well it worked. I tend to go under the boat every week or two anyway, so I'll have a good picture of the growth it allows.

Great buy this paint came with everything needed to complete the task. I painted my 23' fishing boat after prepping the bottom, and it covered perfectly.

I have used Underdog for 4 years, sailing in the fresh water Delaware River, saltwater Delaware Bay in the Chesapeake. I have had a few barnacles in saltwater but mostly slime, and a very light slime in fresh water. A quick swipe with a power washer wand and the hull is clean at winter haulout. Underdog goes on smooth, just remember to mix the can well before using as there is some separatiuon of solids and liquids.

Bottom looked great after a season in brackish water in MD. A lot of barnacles on running gear, but not on paint. Great price, especially with the extras in the kit.

I don't have a whole lot to compare this to, but I've used others and this was by far the least effective ... spend a little more, get a lot more.

Have used for several years. Works as advertised. Xylene works well for a thinner. A good value.
