So I have my new jl wrangler, and want to start modding it. Do we need to be careful what metals we attach and where. I believe the JKs had an issue where the aluminum hinges contacting the steel doors caused corrosion. I believe the fix was an insulating sheet between the two dissimilar metals.
From what I read this is called galvanic corrosion. I am certainly no where near an expert, so some metallurgist may come in and say there is nothing to be concerned with. Or maybe having a bunch more aluminum on these JLs we need to pay attention to what mods we put where. Is stainless to aluminum better than steel to aluminum?
Examples:
1: Can I put the doorless mirrors that attach to the windshield hinge if they are stainless? I don't know what metal that hinge is.
2: There are powder coated steel brackets that you can hang your door on the wall of your garage. Is the inside of that door window channel aluminum, or is there some sort of plastic insert in the channel that would insulate the bracket from the aluminum door?
I assume there are several other cases where we attach a steel mod to an aluminum body part. Anyone concerned or is paint/powder coating enough insulation?
Thanks for the help!
