Ospho is 45% phosphoric acid solution compared to Easywoods Fast Etch which is about 10%. Works much faster, doesn’t harm the metal, and if you want 10% solution, just add the necessary amount of distilled water. Much much cheaper than using Eastwoods fast etch, plus you can adjust the percentage if you want. It’s typically about $15 a gallon at Ace.
I’ve used it and our results have varied. Need to say that I’ve applied it to a basically flat surface and it did ok after applying 3 coats. The issue is that it’s like water and will run down any opening and leaves a nasty streak and if left stand it will crust up.

I bought the stuff in a spray can from Harbor Freight for the go karts. Gonna hope it does half as good as this stuff.
I had my fbody Chem dipped, any flash spots after the fact would be sealed up with epoxy primer . 😅
I wonder how that would work on rusty weight plates
I don't see why not ?
