Duralac is used in marine and industrial applications wherever two dissimilar metals are joined to prevent electrolytic corrosion. It can also protect areas that components of the same metal are in contact and where metals contact wood, rubber, synthetic materials etc. Duralac has low solubility in water and will not erode with time, even when subjected to high pressure from considerable water flow.
Use on masts, winches, aerials, batteries, bolts, screws, etc. Best applied by brush.
