Doing stupid things to my elec system...question

I have never been one to slop grease all over battery terminals as it leaves a mess over time. There are spray products that can be used after the terminals are tightened but I have had a good experience with those green and red felt terminal pads that slide over the post before the terminals. They seal the post to case seam, have a chemical acid neutralizer, and can be easily replaced without a lot of cleanup.
