metal boat in water
1915 magazine cover lady boat water good housekeeping metal tin sign. made of iron sheet / tin metal and this vintage style reproduction metal art is intentionally made to appear rusty, discolored, antique, stained, or scratched. that is representative of the state of the original not the condition of the sign.. Regardless of the bottom paint used or the degree of protection conferred by high build epoxy paint, zincs must be used to control stray current corrosion, to which we can become victim with a metal boat, even without an electrical system, due to the possible presence of an electric field in the water having a sufficiently different potential. Unfortunately, aluminum can just dissolve away if put in saltwater, unless you maintain it and watch for other metals (in the water). this happens via galvanic corrosion: when one metal is conductive (like in saltwater) and it connects to a metal which is not, the non-conductive material (the aluminum boat) begins to fall apart or lose atoms..
