Rust Repair From Battery Acid

[Hamo_01]

Hey I'm looking at buying a r33 and the battery had leaked in the boot and they didn't reall clean it up. There is a bit of rust and corrosion. I'm wondering how hard it is to fix it? Is it just cut and patch with the battery acid?

Well depending on just how bad the corrosion is you should neutralise things with Bi Carb of Soda and scrub it well with a stainless steel brush at which point deoxidene treatment IF it is still available to kill any remaining rust, after this coat the battery compartment with epoxy and even bituminous sound deadener to protect the steel work . In reality having someone fabricate a new Battery box is likely a better and cheaper option especially if it is made from 613 Stainless.

A little tip clamping your battery down well on a neoprene pad to help limit vibration which is the usual cause of battery failure will also help limit and acid egress (although many modern batteries are sealed ) from the battery case.

Or drink beer whilst holding wot and dont open the boot to see battery tray...

The above is probably more accurate though im guessin

Seems almost impossible to fix.

Had a Patrol with a busted battery and nothing stopped that chassis region corrosion.

The battery box in mini's used to rust right through, you'd see the battery hanging by the cables.

Use PPC POR15. Follow the directions (cleaning and prepping the surface is the most important part) and use their Metal Ready prep spray too.

Everybody just washes it in water and forgets about it and then goes "oh f**k it's still rusting". Yes, when you leave uncoated steel exposed to the elements, guess what happens!!

POR15 dries like an epoxy, it is rock hard afterwards.
