Trilux 33 is Interlux's new tin-free antifouling paint, ideal for aluminum boats, outdrives, and outboards. Use for bright color or bright white finishes on underwater metals.
Based on the latest Biolux technology for improved control of slime and algae growth, it replaces the older Trilux and Micron 33. Use Trilux 33 below the waterline on underwater boat hulls and parts in fresh, salt and brackish water. It can be applied by brush or roller.
While it is specifically formulated for aluminum boats, engines, and drive parts, Trilux 33 works quite well on fiberglass, wood and other underwater metals.
Available in Black, Blue, and White colors in Quart and Gallon sizes. Pint size is available in Black only.

No Sand System - Apply one thin, continuous coat of Interlux Fiberglass No-Sand Primer. Sanding System - Sand with 80 grade (grit) paper. Remove sanding residue. Wipe with Fiberglass Solvent Wash 202.

Excellent product, worked and covered as expected. The price was a bit higher here than other suppliers.

Have used Trilux on my outdrive (pacific northwest), for many years now, and as long as one follows their instructions carefully, and do the proper prepping, it holds up well till I re-do it a year later.

I use this on my pontoon boat. My boat is always in the water. Gulf saltwater. I have someone come scrape my boat monthly. I take it out yearly for a thorough cleaning. This stuff works. I still get growth but notice it is a lot less with this.

Trilux 33 bottom paint is made for aluminum hulls and the red color fits my requirements for my classic Chris Craft Roamer. With 41' x 15' to cover I found it easier to work with if I added a small amount of the Interlux 216 thinner as I worked around the hull. Foam rollers will break down so use a thin nap not made from foam. The new bottom paint can be reapplied over the old paint but should be cleaned of all dried scum with a light sanding or wiping with a cloth drenched with thinner.

Use Jamestown's own product for lower units or outdrives. The interlux product is just messy to be around. Gets all over the boat.

This is the best antifouling paint for aluminum hulls that I have found since they banned the tin formulas. I use an automotive primer over the bare spots then put on the Trilux 33.

This paint protects reasonably well against slime. It is totally useless against barnacle and mussel growth.
