Designed for fiberglass, wood, steel, and iron hulls, it offers 500 sq ft coverage per gallon with a durable, flat red finish that resists trailering and beaching wear.

## Description

TotalBoat Underdog Marine Antifouling Bottom Paint for Fiberglass, Wood and Steel Boats (Red, Gallon)

## Features

- ECONOMICAL ANTIFOULING BOTTOM PAINT provides excellent single-season protection; copper biocide keeps barnacles and mussels from clinging to hull bottoms; ideal for sailboats, power boats, fishing and work boats in all types of saltwater conditions
- EFFECTIVE MARINE PAINT prevents barnacles from attaching to your hull by releasing fresh biocide as water moves under the boat; best for boats used frequently; durable finish withstands trailering & beaching better than traditional ablative paints
- FOR USE ON PROPERLY PREPARED FIBERGLASS, WOOD, STEEL, AND IRON BOAT BOTTOMS; because the ablative coating wears away during the season, there's no paint buildup, which makes your bottom paint job easier next season
- EASY TO APPLY: Use a natural bristle brush, or a 3/16” nap or foam solvent-safe roller, or use airless or conventional spray equipment. THINNING (10%): brush/roller - TotalBoat Special Brushing Thinner 100; spray equipment - TotalBoat Spray Thinner 101
- AVAILABLE IN GALLON SIZE IN BLACK, BLUE AND RED COLORS. Coverage: 500 sq ft per gallon; this product is a marine paint intended for antifouling use on boats, applied to hulls and boat bottoms below the waterline only; it is not intended for household use

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best bang for your buck if you know what your doing ..
*by P***. on June 13, 2019*

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

### ⭐ This paint attracts growth.
*by M***K on May 29, 2018*

Don’t waste your money. I live in Newport Beach CA. After spending a ton of time prepping and doing everything exactly right ... two coats etc ... I get a note from my monthly bottom cleaner( that I know and trust for years) after having the boat in the water less than 1 month . he told me my bottom is covered in brown and asked me what kind of paint did I just use. He said the paint job was beautiful but he had never seen paint attract so much fouling so quickly , even more than a bottom with no paint. He said all I can do is have the bottom cleaned twice a month now or haul it and have the bottom done professionally. What a bust ! Seriously ... I relied on all those positive reviews ... all that work for nothing.

### ⭐⭐⭐⭐⭐ Amazing Product Well Exceeded My Expectations!
*by J***R on May 30, 2017*

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!
