I just painted on rust converter, & 2 other coats of undercoating. I was told of this and read up on it, and would like to Tack on zinc, zinc coated, or alumium plates (as Sacrifical Anodes) to your steel structure, acts as the sacrifical metal, so your other steel frame wont rust out, Id like to do this to my Sled Trailer, to help stop rusting, (of course the other issue with the 2 metals touching (which is a no ! NO!) aluminum and steel dont mix, SO my question is anyone know of or did this, what the best metal to use, and where to get it, shd I just go to a Metal Supermarket and by Galvanized zinc coated whatever, or use more aluminum plates.??? The Marine (boat) Anodes could be expensive.
