One note I will add is that I do not use the salt mixed into the vinegar, but I do not have that black tarry slag to clean up either that you see with the salt/vinegar solution. I just use straight vinegar and then soak in a baking soda/water solution to clean/neutralize the process. Im equally happy with the 2nd batch of parts, and will be doing tailgate chains for the matching trailer project next. Pics to come
As you can tell, just a little paint left that will come off easily enough by hand and some 60 grit. Will be getting self-etching primer tonight, then sprayed after my next set of parts are ready.

Jon you really think you`ll need the etching primer, I would think the vinegar should have etched as is maybe a epoxy primer would be good enough.....
By the way I had talked with an old restorer, well older than me, anyways he used to use vinegar all the time until somebody had told him about citric acid, now he uses it exclusively, he reason being he can up the strength, he normally uses a pound per gallon, but that gallon is used a long tme before he discards it, and it don1t smell as bad as the vinegar, he buys it in bulk 5 lbs at a time...
