Best bang for your buck if you know what your doing ..
With all the ablative antifualing paint around for 200 a gallon and up it's nice to see a product come in under 100 bucks that gets the job done !! This one gallon comes with a kit and I was blown away for the price!! Paint try brush roller gloves and jump suit all included in ur shipped box !!! The epoxy and paint are both great I bought both and rarely do reviews unless I'm overly impressed.. some people keep there boats in year round in heavy salt conditions and I guess if that's what ur doing and u want to spend 300 on paint that's great .. but for the rest of us this stuff is nice easy to work with dries strong and the color blue they have is awesome!!! I found this product to do the job exactly as described and with some elbow grease you could really do a nice job with it ... the only negative if there is one is the can was a bit dented like the rest of reviews say but nothing that I thought mattered.. keep up the good product nice to see someone giving u a decent product with extras and not trying to rob you

Poor packaging
Product is great. Shipping poor. Ordered once, it never arrived. Ordered 2nd time and it arrived but the can is so dented that I can't believe it did not leak. I need to use it this weekend or I would return due to condition. I've bought this product before and it always came with a roller, sash, tray, and protective suit. All I received was a dented can.

Amazing Product Well Exceeded My Expectations!
Simply amazing!!! Totally exceeded my expectations. I opened the box and they included for free: a complete roller, tray, gloves, body suit, dust mast, and mixing sticks. All free!!!! I have been bottom painting my own boats for over 20 years and this paint was the best value for the price. It came well mixed and applied very well. My boat has been in the slip for almost 3 weeks now and there is still no single salt line or growth starting yet. For this product I paid $82 plus shipping and again all inclusive with supply materials. Previously at rip off West Marine I would pay $129.99 and still have to buy all the support materials. If you are reading this please trust me I have been doing my own boat maintenance for over 20 years and have learned a lot over the way, many many mistakes included. This product is awesome you will be very pleased!

So far worth the money.
So far a good product, you will need to stir it up really good, 1 gallon covered my 28' boat one coat, I would recommend this paint because of the price point, I'll give another review at end of summer about how well it did or didn't hold uup.my paint cans did come dented, but didn't have any other issues.

Effective, Long lasting bottom paint.
great antifouling bottom paint. I am a repeat buyer, and the first coat far exceeded expected lifetime use. I keep my boat in the water in the Seattle Sailish Sea.

Damaged in transit
One star only because I have not received my order because it was damaged in transit. I hope the company re-ships the paint. I have used this product for 5 years. It works great in the Boston Harbor and beyond areas.

My bottom never looked so good. Eh hem
The 2 cans and the packaged showed up all banged up, but I'm guessing the delivery person was at fault. A fellow boater recommended this paint. I'm glad I listened. Very happy with the process to order, and I'm very happy with the results. Make sure you shake and stir this really well so it's becomes a medium thickness. It goes on fantastic. I have a 268 boat and I used 4/5 of a gallon. One coat looks great, and my bottom was a light green before this, so it hid it well. I would recommend this bottom paint to fellow boaters. In fact my buddy is buying the 2nd gallon I bought to paint his boat.
