Product Details

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!).

Good price, nice accessories
By Pipeguy from NJ

Verified Purchase

Its my first time with this paint, so we'll see how it wears. It went on well for the most part. Certain areas required a second coat once the first coat tacked up. The foam brushes that come with the paint are useless, but that was anticipated.

Bottom Line Yes, I would recommend to a friend

This is great paint I've used it for years but....
By dbinvermont from Burlington, VT

If you order it through Amazon, you don't get all of the extras. Very disappointed. Now i have to buy it all separately.
