I use dielectric grease. It isn't a permanent answer, though. Dealing with the mixer trucks getting water on them every single load and then acid at times, it has been the best help.
On ground cables, I smear it onto the terminal before assembly.
Battery terminals get spray protectant, but that's difficult to get good coverage.
If you found a spray sealer, make sure that it doesn't harden when cured. It would be suseptible to flexing and cracking later, which would let in moisture.
