[quote=jonathan162][quote=dartsailors]Bill, I grabbed a Harbor Freight one last night. My trailer is aluminum and the winch is said to be steel. Do I need to put something between the two when mounting to avoid the corrosion that occurs with dissimilar metals?[/quote]
Sure, if you want to be really anal-retentive over it, but I don't think it's really worth the trouble, because doing it [i]properly[/i] also means isolating the mounting hardware, right? You can put a (plastic, wood, etc.) insulator between them, but are you then going to run a steel bolt through, bringing that fastener into contact with the aluminum? If you use galvanized hardware, has the surface plating sufficiently passivated it to not react with either the steel or the aluminum? Someone smarter than me can answer that question. There are also coatings like Lanacote that help combat that reaction, so if you have a tub handy give it a schmeer before assembly.[/quote]
