DYI plating
On one of the vintage motorcycle forums I frequent, they have lengthy discussions on how to do your own zinc plating. At first glance it seems very simple, but the results have been varied. The bottom line (for me anyway) would be to send it out if you: have a lot of parts to, have a large item to plate (i.e. bigger than nuts and bolts), care about getting a good result, and/or do not want to spend more time and money just to say you did it yourself. I'm not saying don't try it, just forwarding what I've gathered from the experiences of several others. A few finally got nice results after some 'trial and error' failures.
