After seeing all that shiny vintage hardware Nessism, I was spurred to action to apply your methods of preparing parts for plating.
My 550 D1 was crying for a rear wheel hardware refresh.
Though I used Oxallic acid (the same active ingredient in (EvapoRust) the resulting surfaces cry for fresh zinc!
The six P's principle apply, no doubt:.
Proper Preparation Prevents Paltry Poor Performance!
I had a collegue drop the parts off at my local plater last Thursday and I received them back yesterday.
I am very satisfied, to say the least!
Thanks for revealing your method Nessism.
