It’s not difficult to go through the steps. Time to prep the part to a smooth , pit free surface is labor intensive. I probably could have purchased the rocker cover bolts , that were vice gripped to death, but instead filed, and sanded out to 400 grit . As a test , I was happy with results.
The copper bath was not so durable. Buffed off the finish, but as a prep for additional plating, it would definitely work.
The zinc anodes that I purchased were not pure and dissolved quickly. A test of the plating worked however to dull for my taste. Much happier with the nickel , for the same prep.
