Not sure if there is already a thread about this. I'm actually new to the forum thing, I have a 2008 evo x. I replaced the battery awhile back and it built up corrosion all through my trunk. It was an interstate and I read about people replacing the battery with an optima redtop, so I purchased one of them. After about a week, my entire trunk was covered in battery acid again....any ideas on my next step?
