Hey everyone, I just installed my Big 3 in my Scion TC and I was wondering if the copper lugs that I used on my battery and for grounds will be alright and not corrode. Same goes for my chassis ground wire. I sanded it to get clean metal but over time I'm sure it will rust. What can I do to prevent this? I heard about using dielectric grease on it but I would just like some second opinions. Thanks!
