I've been tuning up my car since I bought it a few days ago. Yesterday I removed the battery, and noticed alot of corision underneath where the battery sits from I think a leaky coolent tank. The battery looked great, its recently new, so I whipped it clean and wire brushed the ends to get the little build up off of them. Then I wire brushed and sanded everything on the bottom where the battery sits. I vaccumed it all up and then got some heavy duty rustolium black paint and painted it. It hadn't eaten through the metal yet, but was starting. Do you think what I did should helped prevent any further damage and corision? I'm going to replace the coolent tank next.

 

Do the stuff you just mentioned and you should be good to go.

There is a plastic tray thats available and it should fit in the battery area, I have seen them for more than a few different sizes of batteries now. At least it will protect the metal.

 

This could happen if a battery leaked at some point in the cars life. When I buy a used car, it is one of the places I check for rust. I just did a total rust prevention on my Iroc, and the battery tray got special attention. That tray, brand new, is only about 25-30 bucks, but needs to be welded in. Matt

 

POR-15 is good for that too, it resists the acid in case you ever have a leaky battery again.

 

I second the POR-15, It's a kick A** product, My dad used it in the gastank of his 55 chevy and the stuff has held up for 3 years now. Or try some herculiner.
