The Acid Test
There is a thread on the HAMB about removing rust with a vinegar solution that only takes a few days and apparently works pretty good. I decided to put it to the test and try to de-rust the backing plates from our A-108 van. I used a large blue rubber maid bin with a good fitting lid and four gallons of 5% vinegar that I just happened to have from past pickle making endeavors. These plates were seriously crusty so I decided to forget about them in the slurry for over a week. After that I used a stiff brush and some hot water to scrub away the black slime that is a result of the conversion.
The parts will now immediately flash rust but it's only superficial and comes off easily with a wire brush. After that I used the old Por-15 for an indestructible top coat since I never plan on doing this again for this vehicle. For anyone not in the know, Por-15 is a fairly over priced paint of a nearly impenetrable nature. If you don't believe me then just try to grind some off after it is cured, it takes some serious effort with a grinding wheel to even touch it.
Now we're all ready to assemble the brakes and get the axles mounted in their final homes.
