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!).

Can I use on a plastic float
Typically plastic floats are made of Polyethylene and paint will not stick to it.
Will underdog bottom pain work well for a 88 montego 2757 that is trailered? Looking to save a little over the krypton. Big price difference, would underdog at least last for a season or would trailering be to hard on it.Thanks. -jeff
Hi Jeff, if the boat is on and off the trailer a lot, it may wear the paint away where the bunks/rollers are. If you trailer constantly, you may be better off with a hard paint. Solvent based copper type paints are also going to be rendered inactive after they come out of the water, as the copper will oxidize (you could Scotchbrite the surface when you need it to be active, but that's another process to perform). So if you need the paint for color, you may just want a hard paint, but if you need antifouling protection as well, you may want to look at the copper-free paints or water-based copper paint.

Is it oil or water base?
Oil-based, I believe.
Oil Sent from my iPhone
This is an oil/solvent based bottom paint.

can I use this product to paint the bottom of a fiberglass boat ?
very easy to apply
Very easy to apply
Yes you. It is very easy to apply.
how much dry time?
As I recall it dried within a few minutes to the touch. I really don't know how long it took to cure. We usually got up to Erie to wax and paint one weekend and then another weekend to put her into the water so by then it was fairly cured I'm sure.
On a good drying day a few hours seems sufficient. After one (maybe two) hours it is dry to the touch. That said I did not have opportunity to see if "dry to the touch" is dry enough to launch. But my guess is that it is.
Is there such a thing as Gelcoat in an aerosol spray can??????
I really don't know.
Hello, I do not know whether Gelcoat in an aerosol spray? I bought in galons primer and galons Gelcoat container last year. Please ask direct in store,they know best!
Hi Joseph: I personally have not heard of gelcoat in an aerosol form. That might be answered better by a fiberglass repair shop that specializes in boats. Dana
Not sure.... Your question is posted in an area about bottom paint... maybe try posting it in an area dealing with top coat or gel coat
Is this what became of Bottomkote pro???????????
Bottomkote Pro, an Interlux product, is apparently no longer available. I have used TotalBoat Underdog for the last two years on a wood Grand Banks boat in Greats Lakes fresh water with good results, strictly a one season paint. I would assume that they are pretty similar paints in content and usage. It all depends on your local waters. Good luck.
It works very well and reasonably priced. I used it on 33 ft Egg harbor sport fish. Will do some. Touch up soon. Call total boat to find out about underdogs predecessor Captain wheeler
How's underdog anti fouling paint for freshwater boats?
Great stuff has been on my boat for a year n no growth
I do not know. I've only used it in salt water and it was useless. After less than 12 months, the bottom was totally covered in barnacle. I was very disappointed but it might work in fresh water.
It works pretty good on algae slime in the partially salt water Im used to.Expect to give your boat a soft brush down about halfway through your season.For the price I have no problems using this paint against barnacles and slime and I have a working fleet of 15 boats.
I used my boat in brackash water, after 6 months of leaving in a slip the bottom was free of any growth
I can't answer your question exactly about fresh water because I use my boat exclusively in salt water. My boat is also kept on a trailer. I put two coats on my boat and it looked as good at the end of the season as it did at the beginning. I only plan to roll one coat along the sides, under the boot stripe for this coming season. Highly recommend this product.
With two coats, will this paint last two seasons with the boat left in the water? Mid-Cheseapeake bay region.Bill
I use Underdog on a wood Grand Banks here in the Great Lakes and it works well as a one season paint for me. For multi year use in your area, probably upgrading would be better depending on your hull and local waters. Our glass Chris Craft got two coats of JD Select in 2014 and will only need touch up this spring. Have a nice season.
Hi BillI do one coat a year. I always question the need, it seems that i could go a second year on it. Having said that, by boat is out of the water (and is pressure washed) for the winter. My guess would be yes, it would probably last two years with two coats.BTW, the coverage is suprisingly good. My boat is a 30 ft with a fin keel, and it takes about a gallon for one coat.Good luck!-DaveLake Champlain, VT
Yes. Worked for me. Left the boat in the water all summer, out for the winter, and back in the whole next summer. Very good value for the price. Application was easy, used one gallon for two coats on a 26 ft. Sailboat.,
Not sure about salt water but it will in freshwater (Midwest lakes)
Bill,I'm afraid I don't know of a clear answer to this. The paint is designed to wear off, so it's dependent on too many things.I wouldn't spend twice the money and effort on the chance.
I do the last two feet just below the waterline each year. The rest is good to go
Two seasons with the boat out of the water for the winter in between, at Buffalo N.Y.

Couldn't say: I paint every season and Long Island sound is probably different than Chesepeak!
Underdog Bottom Paint
Have used for several years. Works as advertised. Xylene works well for a thinner. A good value.
The box came with everything you need to paint included.
LBI New Jersy
Excellent for my needs
I have a Fresh Water Boat that is trailered. This is the perfect product for the application. What amazed me was that not only did Jamestown send the paint at a very inexpensive price compaired, they also included a roller, tray and a full set of coveralls to wear, without increasing the price.
Canyon Lake Texas
Generally a good product.
I ordered 4 cans of black and 4 cans of red after that. No problem with the black however 2 of the 4 cans of red were not the same formulation. The viscosity of that product was too thin to stick to the boat and ran through the hull paint leaving our boats to be repainted. I think it was a batch error and doubt there is enough copper to stop barnacles. Otherwise if the quality is monitored by Petit it shouldn't be a problem. We've had success with the paint otherwise.

I will buy this product again!
Good coverage, not as sloppy/drippy as I expected. Time to launch!
Grand Haven, MI
We order every year. Awesome company, great products, easy online ordering.
It hit the spot!
Amazing how easy it was to apply.

Great bottom paint for boat
Went on smooth. Everything included in the order was spot on.
Grady White Mike
Awesome and very inexpensive
This bottom paint which I've been using for quite a few years now is great. What does grow on the bottom during the Season washes of very easily
John the Ocean guy
I would buy this product again.
26' sailboat: the gallon needed to be stretched thin to get two coats, but made it with none to spare. Will be used in New England, little curious to see how the economy paint holds off foul, but need to strip a lot of bottom paint off next year, so didn't want to spend a ton of coin this year on paint.
