We tried some Evapo-Rust on some Datsun parts that were rusty. Spoiler — we were pleased. If we had known how pleased we would be, we would have photographed the parts before we put them in the Evapo-Rust so we could show you the difference. Surely, this stuff can’t be new. And, surely someone knows how to make this stuff without buying Evapo-Rust. Granted, all of this reveals more about my own personality than anything else, as I get stuck at “There’s nothing new under the sun” too easily. I suppose it means something that even if I could make it myself, I’d still probably just go buy it already done, just like the guy who pays for 50% coolant and 50% water. Should I be ashamed? I’m not sure and there are other things worth thinking about, so let’s not get stuck. Rusty parts you say? Evapo-Rust is worth a shot.
