In my world, I would just insulate the two mating surfaces from touching.
PVC sheet, gasket material, duct tape, anything you have that will be somewhat waterproof.
Like you said, it is not permanent . . . . insulation is the key word.

Yep, and it can be permanent if you isolate. For example, I have a snowmobile trailer that is all aluminum, but the axle mounts are obviously steel. A pad of rubber between the frame and the axle mounts takes care of it.
I fish, therefore, I am.
