SPRING MAIL-IN REBATE: Save $50 per gallon on Black Widow!

Pettit Black Widow bottom paint is a slick, hard, high-performance bottom paint that can be burnished to a gun-metal mirror finish for maximum speed. Its advanced, dual-biocide formula provides excellent multi-season antifouling protection against hard and soft marine growth in fresh, salt, and brackish water.

Developed for racing sailboats and speed-hungry offshore powerboats, this dual-biocide antifouling paint contains four slickness-enhancing agents that ensure optimum performance and make the surface easier to keep clean. Apply by brush, roller, or spray on fiberglass, wood, steel, cast iron, most underwater metals, and previously painted surfaces below the waterline. If desired, thin with Pettit 120 Brushing Thinner or Pettit 121 Spraying Thinner. Just 2 thin coats of Black Widow are required for best adhesion and antifouling performance.

Available in Black and Dark Blue in Gallon sizes.

Wouldn't use any other bottom paint!

4 years ago
Applied 3 coats Total Boat hIgh-build epoxy barrier primer, then two coats Pettit Black Widow in dark blue. Messy job, yet, well worth the effort. I couldn't be happier with the results. I found that ambient temperature and humidity changes will have a big effect on dry times and how to much thinning is necessary. Overall, the finish is extremely smooth/slick and is unbelievably hard. I won't ever use another bottom paint. I'm impressed!

Superior in southern waters

I use Black Widow as bottom paint on our J/122 saltwater racer/cruiser. Our racing season on the TX Gulf coast ended in November, and due to COVID-19, we haven't sailed or done maintenance on the boat (which is about 250 miles from our home in North Texas) since then. Because I had been so lax on the maintenance, I had a diver clean the bottom in mid April (that's a full 5 months). I was scared that the bottom was going to look like a jungle. Diver report came back as very light growth with basically no barnacles. I am hugely impressed with the antifouling properties of this product. Miles better than VC Offshore. I can't tell you which bottom is faster, but they both look quite good and feel very smooth once burnished out.

Great product, will keep using it.

5 years ago
I bought a 28 ft boat that was lift kept with no bottom paint. I boat in the Chesapeake Bay and I don't have a lift so it stays in all season. I've owned other boats without bottom paints and tried other non paint products, none seem to work. I didn't want to paint the bottom but being that I keep it in all season and the water is conducive to a lot of marine growth I decided I had to do something different. I read up on the Black Widow and saw the video and decided to give it a try. I prepared the bottom of the boat with Pettit's Sandless Primer which went on very well. Using a 1/8th roller I applied the first coat let it sit for the prescribed time then added a second coat. I did not barnish between coats and it used just over 1/2 gallon. I put my boat in the water in April and you can feel how slippery the paint was with your hand. During the summer letting it sit for a week or two some scum would adhere to the bottom but after a little run that scum came off and was slippery again. At the end of the season which is November I pulled the boat and was amazed that there was no growth on the painted surfaces just a slight scum from sitting for a month before it was pulled. After a quick power wash to remove the scum I could see that the ablative properties were working because I could see thin spots in the paint, no barnacles though. The second year I used a Scotch Brite and water and went over the existing paint very easily, I just wanted to remove the winters dirt. I applied 2 more coats and again the same results as the previous year. Great product.

Hard, slick paint!

5 years ago
I've just gotten done with a complete bottom job on my 1994 J80 (hull #90). This included an extensive blister repair, barrier coat, and then Black Widow. First, I would say this paint has a tremendous amount of solids in it. When you open the can, expect to see a big black glob. You need to stir this with a heavy duty, metal stirring rod on a drill. I broke two plastic stirrers that did just fine mixing up pretty heavy Interlux Interprotect HS. I had a gallon of the BW, poured off a bit, and then mixed it for 20 minutes straight. When you think you've mixed it enough - you're about half way there. I put some on from the first mix, and it was not a smooth application. However, after mixing it for 20 minutes and then thinning it with Pettit 120 (10%), it went on smooth and even. I used the foam cabinet rollers to apply and 4 coats went on great. Took just over a gallon to do the bottom and rudder. After letting it completely dry for 48 hours, we started sanding. I'm sure I could have put in the water at that point and it would have been much better than the 25 year old bottom that was on before. But we started sanding with 400 grit dry, then moved to 600 wet, followed by 1000 wet. Critical spots (rudder, keel, and the first 3-4 feet) got extra hand treatment of 1200, 1500, 2000. I tried burnishing with rubbing compound as the video shows, but this just made a mess. I used 3M rubbing compound (no wax) but it ended up with a waxy finish, so that got sanded off. I haven't gotten back in the water yet but looking forward to some speed improvement, especially in light summer breeze.

Black Widow - Fab Alternative to VC-17

5 years ago
Over-coats over old paint - no stripping, just sand with 80, paint a few coats, burnish and you're ready to go. Half gallon (two quarts) gave us to coats on our 22 foot mini-tonner. This was so easy versus applying VC-17

Q: After two seasons on the original application of Black Widow over an epoxy barrier coat, high wear areas are beginning to show through. I can't find instructions for recoat, specifically what grit paper I should use to prep the bottom. Please advise on where I might find this information, or your recommendation. Regards.

2 Answers

A: According to the data sheet, Pettit recommends sanding with 80 grit. The tech sheet can be found under the tab labeled ""Data Sheet"" on the Black Widow page at the JD website, or at this link: https://doc.jamestowndistributors.com/userportal/pdfs/Pettit/pettit_black_widow_1869_tds.pdf

Q: Black widow, is this recommended for aluminum hulls. Do you need a primer coat? How long will it last?

a year ago
1 Answer

A: Black Widow can be applied to aluminum by following Pettits specific instructions. It is a multi season paint so you will get one season with every coat you add. The more coats you , the longer it will last. You can get more info about applying at this link: https://doc.jamestowndistributors.com/userportal/pdfs/Pettit/pettit_black_widow_1869_tds.pdf

Q: Can BW be applied over CSC if prepared correctly?

2 years ago
2 Answers

A: Petit has changed their position on this. There is a newer compatibility chart that indicates BW can be applied over durable ablatives like the Micron product line provided a heavy sanding is performed. I spoke with the Petit tech folks and they confirmed this.

Q: Can we paint brass props with it?

A: Sorry Tyler, I did not like this product so I removed it from my boat bottom and went back to colored gel coat. I personally don't think that it will hold on to the prop, unless you apply Interlux 2000/2001 barrier coat epoxy, first. Good luck.

Q: Can this paint be used to paint an out drive?

1 Answer

A: Yes, we used the Black Widow for our Fountain 38 EC, both for bottom paint as well as the Bravo 3XR out drives and k-planes. The paint holds up great, virtually no barnacles after spending 7 months in the water. Minimal retouching needed for next season.

Q: I have this on a J80 in an inland lake in NC. I clean the bottom every week and the brown slime is easy to wipe off - but there is still a ""slime"" on the paint that feels like it has different thickness in different areas. My question - is this the graphite and other slickening agents or some growth that needs to cleaned off. I rolled 4 coats of BW over 4 coats of Interlux HS barrier coat. I sanded the BW with 300 working down to 2000 on the keel, rudder, and bottom forward of the keel. Thanks.

A: When I pulled my boat last year after 3 month in an inland lake in TN the bottom looked great but did have a thin layer of growth/slime that came off pretty easily with a power wash and wipe down. The BW held off the slime much better than Baltoplate which I have also used.

Q: What thinner to use? Should it be thinned to spray?

5 years ago
2 Answers

A: Yes ,You will have to thin to spray..I rolled it and I even thinned it..I wish I would of sprayed it..I'm sure it would of laid alot flatter..BUT I sanded it between coats with 400 litely..Which wasted some of the product. I used just general lacquer thinner and It seemed to work fine..Where I couldn't get with my speed roller I used one of those small throw away Chinese brushes..BUT it doesn't lay down real good so u have to burnish with 400 after to flatten out. Hope this helps Pat

Q: What is the best way to apply (not spraying) to start with a smooth surface? I used a thin roller but still got an orange peal finish that required sanding half the material off to even begin to try and burnish. It took forever. Should it be thinned and a foam brush used?

A: It can probably rolled (thinnest nap you have) and tipped but I had same luck as you just rolling. My next attempt is to spray. Let me know if roll and tip works.
