Others sell "Made in US" zincs from such companies as Camp and American Anodes. Is there a difference in how long they last? RC Using how long zincs last is not a good measure of their quality. Zincs with impurities or improperly alloyed zincs last a long time but do not do the job they are intended for. They are supposed to dissolve when installed properly. The best advise is to use zincs that are in accordance with the appropriate Mil spec. If the zincs on your boat are not wasting away then something else on your boat is.
