I used to do a lot of plating (about 40 years ago) on various parts to
prevent oxidation. I would now like to
chrome or silver-plate some components on my ultra-light engine.Please
forgive an Old Mans memory, but
I have forgotten what kind of acid to use in the plating solution. I would
sure appreciate any help.
Thank you
Chuck
