Interlux Micron Optima Bottom Paint

Micron Optima is a water-based antifouling paint that provides multi-season protection. Interlux's powerful Biolux additive blocks algae and slime in even the worst fouling conditions. Optima is compatible with most other bottom paints. Its low odor, low VOC water-based formula makes application and clean up easy. Water-activated formula means you can paint in the fall and launch the following spring. Use on fiberglass, wood and primed underwater metals (except aluminum) in all waters.

Optima is an ablative or self-polishing paint that wears away with use to constantly expose fresh biocide. This keeps the finish smooth and minimizes paint build-up, in the name of easier maintenance and improved fuel efficiency.

Sold in gallons in your choice of Black, Blue, and Red. True color will develop after immersion.

worked great for us.


We've had our boat down South in the winter (FL and Bahamas) and this worked great over the past 2 seasons. The boat is hauled for the summer. It does take a lot of stirring to mix it and make it smooth. It also doesn't have a real strong odor.

I would not buy this product again


Paint in newly opened can was very thick and off color. After extensive mixing the color improved but contained lumps that would not come out. Nevertheless I added (white) activator which after mixing turned the color to near pink (as opposed to dark red ). Hoping that the color would darken after drying I painted a small section of the boat bottom. The color remained the same - PINK!
