Back in the day many people would put a thin coat of petroleum jelly on their battery connections to keep corrosion at bay. I’ve personally never used it but on my wife’s new/old 2008 Pontiac Solstice GXP with the 2.0T the negative battery cable connection was corroded so bad I ordered new cable ends. I remembered that mechanics and diyers swore that Vaseline would help fight terminal corrosion but with the turbo and extreme under hood temps I’m thinking it would just melt away after a few drives. Is there any modern alternatives to Vaseline available today or might the Vaseline actually work in this hot environment?
