I had terrible battery terminal corrosion on my Tundra for years. I tried several different lubes on the terminals with no luck (di-electric, motor oil, Vaseline, Fluid Film, etc). Got to the point where the positive connector corroded to nothing and I had to replace it. Battery was strong so I was reluctant to replace it. I finally came to my senses and replaced the battery and haven't had a bit of corrosion since. I think its been over a year now.
