Interlux Trilux Boat Prop & Drive Antifouling Spray Paint

Props and engine drives are constantly being submerged in water, which can cause a breakdown of the metals or corrosion. Protecting them is key to long-lasting props and drives. Interlux has a specially formulated antifouling spray just for props and engine drives. Trilux prop paint helps protect the vital parts from the underwater elements and keeps them up and running season after season.

Trilux prop paint is a high-quality antifouling spray paint designed just for aluminum outboards and outdrives but is safe for all underwater metals. Made with the Interlux Biolux technology, it prevents slime, algae, and other organisms from attaching to your props and engine parts. The highly effective controlled-release film technology in the Interlux Trilux prop paints helps deter these elements.  For optimal results on bare metal, prime with Primocon first to ensure best results.
