Product Details

Interlux InterZinc is an aerosol spray designed to protect underwater metals on all kinds of boats. Use on stainless steel, aluminum, lead, steel and bronze. Easy to control spray nozzle ensures paint goes where you point it.

Fast drying formula creates a smooth, hard surface that acts as a barrier to protect keels, shafts, props, outdrives, struts, rudders, trim tabs and more from barnacles and corrosion. In controlled testing, one coat of InterZinc provided greater protection and better performance than 2 coats of the competition.

16 ounce aerosol can is available in gray finish.
