Wisconsin | I haven't watched the videos, so don't know exactly what they're claiming. I'll dip rims or other parts in a bath of rotten corn that will lift rust, take them out, pressure wash and they'll instantly flash rust. Brush on phosphoric acid, even weak, and the rust disappears, miraculously. Anything that has thicker rust the acid is marginally effective, it helps paint stick where the metal is clean, but phosphoric acid over anything that doesn't come off is fooling yourself. | |
