Re: Stopping or Reducing trailer corrosion ??


The farther two metals are apart in the Galvanic series the more the baser metal will sacrifice itself to the nobler metal. Be careful when mixing metals underwater, especially in salt or brackish water, and use sacrificial anodes baser than any metal you want to keep:
