Battery was leaking.  I need to remove the Rust from the battery pan of my car. I can use a wire brush on the parts I can reach, but I need a chemical that will neutralize the rust I can't reach, and provide a good surface to paint. The chemical has to be harmless to the wires, hoses and belts that are near the area. In addition, it should be water soluble so I can hose it out, dry it and paint it. Also, what type of paint/primer/sealer is best? It's a semi-collectible car, so I want to do it right. Thanks in advance. You guys have never let me down.

Good thread, but I can't use the electrolysis method. The parts are welded inside my engine compartment. |

Quoted: They sell some stuff in the hardware store out this way called Naval Jelly, (ok, get your yuks out now...  ). It does what you're looking for. Neutralize the acid first though.Naval Jelly (phosphoric acid) was my first though, but I was wondering if there was a better product on the market by now. Can anybody recommend a paint or primer to use? There is still going to be some rust in areas under the pan that I can't reach. |

This is great for rust on car sheet metal:

I had the same thing happen with a sidepost battery from the terminals being tightened down too hard, causing the leak.
I used this stuff: Permatex Rust Treatment 
Two years ago and the rust hasn't showed back up yet. I just brushed the stuff over the rusty places. Didn't even paint over it. It turns black anyway. |

Quoted:
Do they sell those at harbor freight? Quoted:
Bake out cycle in a vacumm furnace.. Works everytime its tried.. Just make sure you remove any aluminum or zinc first.. Eutectics can be a real bitch sometimes. You can buy used small ones but they can get prety pricey. The ones at work range from $750K to $2.5M. BTW.. Rust will flash all over the item being heat treated. It sort of fills in the pits in the metal. |

Quoted: 1) scraper and wire brush 2) naval jelly 3) rust converter 4) corrosion resistant paint +1. Wash the area with baking soda and water and then soapy water to eliminate the acid residue. Remove any rust scale with a wire brush. Use a rust catalyst, home depot/lowes and almost all parts stores have it under different brand names. Ospho, "Prep and Prime", "Prep and Etch", "Right Stuff" etc, any variation of rust catalysts with phosphoric acid will do it. Let the area dry after cleaning scraping, use a brush to douse it liberally with rust catalyst, let dry and paint with rustoleum spray paint, let dry and spray with a can of automotive rubber undercoating to prevent future mishaps. profit? |
