Rust remover - more amazing uses!

The other thing I needed to attend to was to get the surface rust off of the battery tray. On the early Vipers the battery tray is underneath the trunk floor, welded to the right rear frame rail and pretty much unaccessible from the top or bottom. I rigged up a curtain of plastic around the battery box and folded it into a bucket. I then used the sump pump and a hose to a spray head and routed that into the trunk to spray the liquid over the tray and down the curtain into the bucket, where it gets recylced back again. I just let it flow for a few hours and it works very well.
