TotalBoat Underdog is a dependable, solvent-based, single-season antifouling bottom paint that provides outstanding protection at a very affordable price. Its ablative action is designed to work most effectively on boats that are used on a regular basis.
Extensive testing has proven that TotalBoat Underdog provides excellent protection against barnacles and other antifouling pests in all water conditions. Ablative technology allows the surface to polish away over time, minimizing paint build-up as well as releasing fresh layers of biocide as the season progresses. Underdog has excellent adhesion to fiberglass and wood.

can I use this product to paint the bottom of a fiberglass boat ?
Yes you. It is very easy to apply.

how much dry time?
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.
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.
What is the copper content of Underdog Bottom Paint?
Copper content is around 27 percent and seems to have a lot of talc in it. I had a diver in to clean the bottom last week and it had very little growth and only a few small barnacles on the bow in the sunny area. My boat is in brackish water in Florida and is hauled yearly for paint. I didn't want to spend the big money every year and I think this paint will be just fine.
product info says 21%
Is there such a thing as Gelcoat in an aerosol spray can??????
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
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
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!
I really don't know.
Is this what became of Bottomkote pro???????????
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
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.
How's underdog anti fouling paint for freshwater boats?
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.
I used my boat in brackash water, after 6 months of leaving in a slip the bottom was free of any growth
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 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.
Great stuff has been on my boat for a year n no growth
With two coats, will this paint last two seasons with the boat left in the water? Mid-Cheseapeake bay region.Bill
Couldn't say: I paint every season and Long Island sound is probably different than Chesepeak!
Two seasons with the boat out of the water for the winter in between, at Buffalo N.Y.
Don Last Name
I do the last two feet just below the waterline each year. The rest is good to go
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.
Not sure about salt water but it will in freshwater (Midwest lakes)
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.,
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
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.
Would this paint be ideal for a trailered boat? I have a 19 flats boat that needs to be painted over the gel coat would it stick to gel coat?
It works on my 1978 Hunter Sailboat, which is fiberglass, on the bottom.Not sure it stick to the sides if that what you are asking. Buy one can and try it.
IY WILL BUT I WOULD PUT A LIGHT SANDING FIRST, WHEN YOU PUT ON A SECONDCOAT JUST WASH THE BOTTOM FIRST
I can't really say,but it will stick to a barrier coat if you put one on, and the barrier is great in preventing blistering in the gel coat
Thanks ED. My question was will it stick to gel coat or does all the gel coat need to be sanded off? My boat doesn't get stored in the water, it is trailered to the ramp then trailered back home. I wanting to know if that affects the paint at all being out of the water? Thanks again.
The bottom I sand before I apply this paint. Plus I do it every year.But my boat is on land in a boat yard for 1/2 the year. It sticks there.
Sticks well to gelcoat....used on my sailboat for past three years in fresh water....great product.
The tech data sheet lists a "Launch WIndow: within 2 weeks of painting." What does this mean?
I believe that means "for best results, launch within two weeks of paint application"
I can't answer that question, I assume it meant don't put in water until the paint has been on the boat for 2 weeks before putting the boat in the water. It was many weeks before I put my boat in the water, so far the paint has held up well. My boat is a three point hydroplane and has only been in the water twice. Sorry I don't have any more information to help you, Good luck.
I have used this paint for several seasons and have put the boat in the water about a week after paint application, weather permitting. I am not sure what the two week window is for, but it must have something to do with the drying process and also that overexposure to air might cause unwanted oxidation of the copper compounds thereby. But I am bot familiar enough with the paint chemistry. Also, I have had no more than one season protection using this paint; less if it is in the water full time.
Once you paint the bottom.....you have two weeks to get it in the water.
To be used in spring
I will not be using until spring 2018, and will not know how effective is is until fall 2018.I have used Underdog previously and have been satisfied.
total boat workskiff
great products and servicebuilding lou's workskiff with all total boat products
Great Value, Great color
Easy to use high quality, excellent value. I like the maroon color better than the bright reds that other companies offer.
This is the best antifouling paint I have ever purchased.
It is the third week of August and I have no growthon the bottom of my boat. You can't beat the price,and they even included a full painting kit.This was a five star purchase.Thanks
Not great in high growth areas
Applied one coat over existing ablative paint. Easy to apply and loved all the extras and free shipping. Had the boat hauled after 2 months and found considerable growth on the bottom, no barnacles just a thick layer of grass. Boat was used about once a week. Will be upgrading to a higher copper paint next season.
Value -- for the price best value on the market
Easy to apply in small areas and trim lines
Raystown Lake, Pa.
So far I would by this paint again will let you know .
The paint kit I received had a broken roller pan .
Good product, good price
This was originally used on a sailboat that was previous bottom painted and used in salt water. We were using in fresh water only. Not knowing what bottom paint was used previously, it took a lot of sanding to remove all, some patching and a good solvent wipe before applying. Like anything else, you need a good foundation, don't skimp on the prep. I applied 4 coats and it looked great. Each spring I'd give a quick sanding to remove the shedding and smooth it out, then apply 2 fresh coats. Paint did it's job and was reasonably priced. The blue color we selected was a big improvement over the old brown too. Would recommend for sure.
I would buy this product again
First time using this product. Coverage was good on the bare spots. Will see at the end of the season how it holds up
Used this last year on our '86 268WE and absolutely LOVED it. It went on easy and in short time, all we had to do was sand a few areas. It held up cleanly against the filth of the Ohio haha. Recently bought an '89 340DA and plan on using this for it. As compared to other paints on the market......GREAT BANG FOR THE SMALL BUCK!! just mix it really good and give the can a few shakes and inversions
